What is the value of x in the equation 3/4x+2=5/4x-6
Solving for x...
3/4x+2=5/4x-6
8=2/4x
8=1/2x
x=16
To find the value of x in the given equation, we can eliminate the fractions, combine like terms, and solve for x. The value of x is 16.
Explanation:To find the value of x in the equation 3/4x+2=5/4x-6, we need to isolate x on one side of the equation. We can do this by first getting rid of the fractions. Multiplying each term in the equation by the LCD (Least Common Denominator) of 4 will help us eliminate the fractions. Then, we can combine like terms and solve for x.
Multiplying both sides of the equation by 4, we get: 4(3/4x+2) = 4(5/4x-6), which simplifies to: 3x + 8 = 5x - 24.Next, we can subtract 3x from both sides to isolate the x terms: 3x + 8 - 3x = 5x - 24 - 3x, giving us: 8 = 2x - 24.Then, we can add 24 to both sides of the equation to further isolate x: 8 + 24 = 2x - 24 + 24, which simplifies to: 32 = 2x.
Finally, we can divide both sides by 2 to solve for x: (32/2) = 2x/2, resulting in x = 16.

Find the value of x that makes ABCD a parallelogram.
Answer:
x=70
Step-by-step explanation:
I'm pretty sure the sum of all angles has to be 360°
and 70+70+40+40=220
so 220+x=360
we figure this out by taking 360-220 which equals 140
and then we divide 140 by 2 which is 70.
To double check, if you add 70+70+40+40+70+70, it equals 360.
The value of x from the given parallelogram is 70°. Therefore, option B is the correct answer.
What is parallelogram?A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.
Given that, ABCD is a parallelogram.
Here, ∠A+∠B+∠C+∠D=360°
70°+x+40°+70°+x+40°=360°
220°+2x=360°
2x=360°-220°
2x=140°
x=70°

Simplify completely quantity 12 x plus 36 over quantity x squared minus 4 x minus 21 and find the restrictions on the variable.
a.) 12 over quantity x minus 7, x ≠ 7
b.) 12 over quantity x minus 7, x ≠ 7, x ≠ −3
c.) quantity x plus 3 over quantity x minus 7, x ≠ 7
d.)quantity x plus 3 over quantity x minus 7, x ≠ 7, x ≠ −3
Option B
12 over quantity x minus 7, x ≠ 7, x ≠ −3
Solution:
Given that we have to simplify quantity 12 x plus 36 over quantity x squared minus 4 x minus 21
So we have to simplify,
[tex]\frac{12x + 36}{ {x}^{2} - 4x - 21 }[/tex]
We have to find the restrictions on the variable
The above given Rational function is defined, for
[tex]{x}^{2} - 4x - 21\ne0\\\\(x+3)(x-7)\ne0\\\\x\ne -3,x\ne7[/tex]
In order to simplify the above expression, we need to factor both the numerator and the denominator
[tex]\rightarrow \frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ {x}^{2} - 4x - 21}[/tex]
For the denominator, we need to split the middle term of the quadratic to get factored form,
[tex]\rightarrow \frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ {x}^{2} - 7x + 3x- 21}[/tex]
[tex]\frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ x(x - 7) + 3(x- 7)}[/tex]
Fcatoring the denominator part,
[tex]\frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12(x + 3)}{ (x + 3)(x - 7)}[/tex]
Cancel out common factors to get,
[tex]\frac{12x + 36}{ {x}^{2} - 4x - 21 } = \frac{12}{x - 7} \\\\where\\\\x\ne -3,x\ne7[/tex]
Thus option B is correct. 12 over quantity x minus 7, x ≠ 7, x ≠ −3
The simplified expression is 12 / (x - 7) with restrictions x ≠ 7, x ≠ -3. The correct answer is option b.) 12 over quantity x minus 7, x ≠ 7, x ≠ −3.
The expression((12x + 36) / (x² - 4x - 21)) and finding the restrictions on the variable.
First, we factor both the numerator and the denominator.
The numerator can be factored as 12(x + 3).
The denominator can be factored by finding two numbers that multiply to -21 and add to -4, which are -7 and 3.
Thus, the denominator factors to (x - 7)(x + 3). Our expression then simplifies to (12 / (x - 7)), after cancelling out the (x + 3) terms.
To find the restrictions on the variable, we note that the original denominator, (x² - 4x - 21), cannot be zero, as division by zero is undefined.
Setting (x - 7)(x + 3) to zero gives us the restrictions x ≠ 7 and x ≠ -3, to ensure the denominator is not zero.
Therefore, the simplified expression is 12 / (x - 7), with the restrictions x ≠ 7, x ≠ -3.
the concept and full method
Answer:
Step-by-step explanation:
This kinda looks like the limiting definition of a derivative.
Anyway, what we are doing with the f(2 + h) is evaluating f(x) with 2+h in place for x. That looks like this:
f(2 + h) = 2(2 + h) - 3 which simplifies to
f(2 + h) = 4 + 2h - 3 which simplifies to
2h + 1
From that we are subtracting f(2). What we are doing with that is evaluating f(x) with 2 in place for x. That looks like this:
f(2) = 2(2) - 3 which simplifies to
f(2) = 4 - 3 which simplifies to
f(2) = 1. Now put those together over h to get:
[tex]\frac{f(2+h)-f(2)}{h}=\frac{2h+1-1}{h}=\frac{2h}{h}=2[/tex]

The question involves solving a system of linear equations from high school algebra. Substituting Y from the first equation into the second and solving for x, we find that x = -5 and Y = -3.
Explanation:The student is asking about solving a system of linear equations, which is a concept in algebra that falls under high school mathematics. To find the solution to the given linear system, we can use either substitution or elimination methods. Let's use substitution since the first equation has Y isolated.
From the first equation Y = 2/5x - 1, we substitute for Y in the second equation, which gives us 2x - 3(2/5x - 1) + 1 = 0. Simplifying, we get 2x - 6/5x + 3 + 1 = 0, which further simplifies to 4/5x + 4 = 0. Solving for x gives x = -5. Substituting x back into the first equation to find Y yields Y = 2/5(-5) - 1, so Y = -3. Therefore, the solution to the system of equations is x = -5 and Y = -3, which is the point where the two lines intersect.

-1×+10y=8
Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8

B.The coefficient 6 represents the cost of b stems of wood bark.
C.The term 8f represents the cost of f stems of flowers at $8 per stem.
D.The coefficient 3 represents the number of packages of marbles she buys.
Choosing the correct statement:
As the formula for cost of any item can be calculated by multiplying the cost of one item with the total number of items.
So, if f represents the stems of flowers, and the cost of f stems of flowers at $8 per stem. Then according to the formula for cost of any item, the statement C is true i.e. "The term 8f represents the cost of f stems of flowers at $8 per stem" is the correct statement.
Question # 2 Solution
As the inequality is given as:
12x + 9x - 3 ≤ 3(2x + 14)
and we have to find the value of x.
So,
12x + 9x - 3 ≤ 3(2x + 14)
Step 1: Simplify both sides of the inequality
21x - 3 ≤ 6x + 42
Step 2: Subtract 6x from both sides.
21x - 3 - 6x ≤ 6x + 42 - 6x
15x - 3 ≤ 42
Step 3: Add 3 to both sides.
15x - 3 + 3 ≤ 42 + 3
15x ≤ 45
Step 4: Divide both sides by 5
15x/5 ≤ 45/5
3x ≤ 9
x ≤ 9/3
So, x ≤ 9/3 is the right answer. Please note that x ≤ 9/3 can also be written as x ≤ 3.
Hence, option A i.e. x ≤ 9/3 is correct. The solution graph is also attached in figure a.
Question # 3 Solution
As we have to find the correct statements from the given graph that represents John's weight (in pounds) as a function of time t, measured in days since January 1, 2017.
So, here are the correct statements that validate the graph:
The statement 'The independent variable is t, the number of days since January 1, 2017' is correct as t represents the independent variable because John's weight (in pounds) being the function of time t depends on the time t. Hence, time t is independent variable. The statement 'f(t) = 160 means that John weighed 160 lbs. on day 12, 120, and 172 after January 1, 2017' is correct because the output value i.e. f(t) of graph is showing John's weight weighed 160 lbs. i.e. f(t)=160 on the input values of day 12, 120, and 172 i.e. t = 12,120 and 172 after January 1, 2017. The statement 'f(0) = 140 means that John weighed 140 lbs. on January 1, 2017' is correct because the output value i.e f(0) of graph is showing John's weight weighed 140 lbs. i.e. f(0)=140 right on the day January 1, 2017 because t = 0 on January 1, 2017. And the value of t increases after January 1, 2017. The statement 'f(40) = 180 means that John gained 40 lbs. since January 1, 2017' is correct because on t = 40, the graph reaches to 180 i.e. the output value i.e. f(40) = 180 on t = 40. As on January 1, 2017, John was already weighed 140 i.e. f(0) = 140 on t = 0. So, f(40) = 180 means that John gained 40 lbs. since January 1, 2017.The statement 'f(200) - f(160) = 30 means that John gained 30 lbs. from day 160 after January 1, 2017 to day 200' is correct because the difference of f(200) and f(160) is 30 lbs. So, it specifies that on days' intervals from 160 to 200, the constitute gain of John's weight was 30 lbs.The statement 'The most appropriate domain for this function is all integers' is incorrect because when we talk about all integers it means it must have consisted negative integers too. But, as we cannot have negative time or days, and his weight also cannot be negative. So, to say that 'The most appropriate domain for this function is all integers' is not correct.

A discount store normally sells DVDs for $14.44. If the DVDs go on sale for $13.72, which of the following is closest to the percent of decrease in the price?
Answer:
4.9%
Step-by-step explanation:
To find the percentage you first find the decrease in price, divide it by the original price then multiply it by 100.
(14. 44-13. 72)
= -------------------- ×100
14. 44
0. 72
= -------- × 100
14. 44
= 0. 72× 6. 925207759
= 4. 986149584

Write the expression that represents the phrase,
"two times the difference of a number and 17."
Use x as the variable.
Answer:
2x + 17
Step-by-step explanation:
Answer:
2(x-17).
Step-by-step explanation:
The given phrase is "two times the difference of a number and 17."
We need to find the expression for given phrase.
Let x be the unknown variable.
Difference is denoted by "-" symbol.
Time is denoted by "×" symbol.
Difference of a number and 17 = x-17
Two times the difference of a number and 17 = 2×(x-17) = 2(x-17)
Therefore, the required expression is 2(x-17).

If James borrows $4,200 to pay his college tuition. He signs a 5 year simple interest loan. If monthly payments are $78.40, what is the interest rate on the loan?
0.024 /yr
Step-by-step explanation:
Without interest, the monthly repayment would be;
5 yrs = 12 months * 5 = 60 months
$4200 / 60
= $70
James, however, pays $78.40 monthly. The interest therefore is;
Jmaes pays a total of $78 * 60 = $4704 at the end of the 5 years. The formula for finding simple interest is;
A = P(1 + rt)
Where:
A = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R/100
R = Rate of Interest per year as a percent; R = r * 100
t = Time Period involved in months or years
4704 = 4200 (1 + 5r )
4704 = 4200 + 21000r
504 = 21000r
r = 504/21000
r = 0.024
Interest rate = 0.024 /yr

The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than the youngest. Write and solve an equation to find the ages of each sibling
Answer:
Youngest Age = 6
Middle Age = 9
Oldest Age = 12
Step-by-step explanation:
Let youngest age be x
Middle one age be y
Oldest age be z
So,
x < y < z
Now lets come up with the equations using the statements.
Three age combined is 27, so we can write:
x + y + z = 27
Oldest is TWICE youngest, so we can write:
z = 2x
Middle is 3 YEARS OLDER than youngest, so we can write:
y = x + 3
Now we replace first equation with 2nd and 3rd, to get:
x + y + z = 27
x + x + 3 + 2x = 27
We can solve this for x:
x + x + 3 + 2x = 27
4x + 3 = 27
4x = 24
x = 24/4
x = 6
Now finding y:
y = x + 3
y = 6 + 3
y = 9
Now finding z:
z = 2x
z = 2(6)
z = 12
Thus,
Youngest Age = 6
Middle Age = 9
Oldest Age = 12
English muffins are on sale for $1.99 per package, but only if you buy five packages. This is a $1.00 discount per package. What percent do you save off the regular price when buying the English muffins on sale? Round the answer to the nearest tenth.
Answer:
50.3% of profit.
Step-by-step explanation:
English muffins are on sale for $1.99 per package, but only if you buy five packages.
Therefore, the price of five packages of muffins on sale is $(1.99 × 5) = $9.95.
There is a $1.00 discount per package on sale.
So, the ordinary price per package of muffins is $(1.99 + 1) = $2.99.
Therefore, the ordinary price of five packages of muffins is $(2.99 × 5) = $14.95.
Hence, the percentage of profit that I will make when I purchase the package of muffins in the sale is [tex]\frac{14.95 - 9.95}{9.95} \times 100\% = 50.25\%[/tex] ≈ 50.3 % (Answer)
