Answer:

Answer:  2 a + 11

Step-by-step explanation:

Simplify the following:

5 a - a - 2 a - 6 + 17

Grouping like terms, 5 a - a - 2 a - 6 + 17 = (-a - 2 a + 5 a) + (17 - 6):

(-a - 2 a + 5 a) + (17 - 6)

-a - 2 a + 5 a = 2 a:

2 a + (17 - 6)

17 - 6 = 11:

Answer:  2 a + 11

The expression 17-a-2a-6+5a simplifies to 2a+11. This involves combining similar terms and simplifying the arithmetic.

Explanation:

In order to simplify the expression 17-a-2a-6+5a, we first need to gather like terms. In this expression, the like terms are -a, -2a, and +5a. When you add these together, you get 2a. Now, substitute this back into the expression. You now have 17+2a-6. If you simplify further by adding the plain numbers together, you get 2a+11. Therefore, the simplified expression is 2a+11.

Answer:

[tex](3x+5)+\frac{28}{2x-4}[/tex]

Step-by-step explanation:

Since,

The volume of a rectangular prism = Base area × Height,

Given,

Volume of the rectangular prism = [tex]6x^2-2x+8[/tex]

Base area = 2x - 4

Let h be the height,

[tex]\implies 6x^2-2x+8=(2x-4)h[/tex]

[tex]\implies h = \frac{6x^2-2x+8}{2x-4}[/tex]

By long division ( shown below ),

[tex]h=(3x+5)+\frac{28}{2x-4}[/tex]

Which is the required expression that represents the height.

Answer:

[tex](3x+5) + \frac{14}{x-2}[/tex]

Step-by-step explanation:

We are given the following information in the question:

Volume of rectangular prism =

[tex]6x^2 - 2x + 8[/tex]

Area of base of prism =

[tex]2x -4[/tex]

Formula:

[tex]\text{Volume of Prism} = \text{Area of base}\times \text{Height of prism}\\\\\text{Height of prism} = \displaystyle\frac{\text{Volume of Prism} }{\text{Area of base}}[/tex]

Putting the values we, get,

[tex]\text{Height of prism} = \displaystyle\frac{6x^2 - 2x +8}{2x-4} = \frac{2(3x^2-x+4)}{2(x-2)}= (3x+5) + \frac{14}{x-2}[/tex]

Hence, the height of the prism is given by the expression [tex](3x+5) + \frac{14}{x-2}[/tex]

Answer:

6 units away from 0.

Step-by-step explanation:

when move to 6 you count the units.

Answer:

The unit rate is 0.14 cents per ounce.

Step-by-step explanation:

Divide 3.92 by 28 to find out how much the trail mix is per ounce.

The unit rate of Dmitri's trail mix purchase is $0.14 per ounce, calculated by dividing the total cost by the total weight.

To find the unit rate of Dmitri's trail mix purchase, we divide the total cost of the trail mix by the total weight of the trail mix. Dmitri bought 28 ounces of trail mix for $3.92, so we perform the following calculation:

Unit Rate = Total Cost / Total Weight

Unit Rate = $3.92 / 28 ounces

Unit Rate = $0.14 per ounce

Therefore, the unit rate is $0.14 per ounce. This means that for every ounce of trail mix, Dmitri paid $0.14.

Answer:

The answer would D.) 33.5 because 9.5+24 is 33.5 and since vertical distance is always an absolute value, it will never be a negative number.

The vertical distance between the top and bottom of the boat is calculated by summing the distances above and below the lake's surface, which total 33.5 feet, making option D correct.

To calculate this, we consider that the top deck of the boat is 9.5 feet above the surface of the lake, while the bottom of the boat is 24 feet below the surface. The total vertical distance would be the sum of these two values, as one needs to account for the entire distance the boat covers from top to bottom.

So, the calculation would be as follows: 9.5 feet + 24 feet = 33.5 feet. Therefore, the vertical distance between the top deck and the bottom of the boat is 33.5 feet. This makes option D the correct answer.

Hi there!

A valley farmer has 26 employees and he pays each of them $410 per week.

After paying them for one week he has $162 dollars left. We need to find how much money he had at first.

So the first step is to multiply $410 on 26 since he gives 410 dollars to each employee, which he has 26.

$410 · 26 = $10,660

So he had $10,660 before he paid the workers, but he still had $162 left. To find out his overall total of money he had we need to add $10,660 and $162 which will be $10,822.

The farmer had $10,822

Answer:

-88

Step-by-step explanation:

Let N(x) be the number of students at NMS for a certain number of years.

Let S(x) be the number of students at SMS for a certain number of years.

Let x be the number of years.

N(x)=1240-25x

S(x)=800-30x

When # of students is equal, N(x)=S(x). Therefore, we are looking for the value of x (# of years) when 1240-25x=800-30x

Subtract 1240 from each side

-25x=-440-30x

Add 30x

5x=-400

x=-88 years

Answer:

4. The mean and median age are most likely to be same for the students in Math 1.

Step-by-step explanation:

We have been given two box plots that show the ages of college students in different math courses. We are asked to choose the true statement about these box plots.

1. The median age of the students in math 1 is greater than the median age of the students in math 2.  

We can see from our given box plots that median age for both Math 1 and Math 2 is 19 that is represented by vertical middle line of box, therefore, 1st statement is not true.

2. The median age of the students in math 1 is less than the median age of the students in math 2.

Since median ages for students in Math 1 and Math 2 are same (19), therefore, 2nd statement is not true.

3. The mean and median age are most likely same for both sets of data.

We can see that box plot for ages of Math 1 students is symmetric, therefore, both mean and median will be same for Math 1 students.

The box plot representing ages of Math 2 students is skewed right as it has an outlier as 23, therefore, its mean age will be greater than median age.

Therefore, 3rd statement is not true either.

4. The mean and median age are most likely to be same for the students in Math 1.

We can see that box plot representing ages for Math 1 students is symmetric and its whiskers are equidistant from median. So both mean and median age are same that is 19, therefore, 4th statement is true.

Answer:

[tex]\frac{c-a}{2}[/tex]

Step-by-step explanation:

given [tex]\frac{a}{2x-c}[/tex] = - 1 ( cross- multiply )

- (2x - c ) = a ( distribute left side )

- 2x + c = a ( subtract c from both sides )

- 2x = a - c ( multiply both sides by - 1 )

2x = c - a ( divide both sides by 2 )

x = [tex]\frac{c-a}{2}[/tex]

Answer:

x = [tex]\frac{(a - c)}{-2}[/tex]

Step-by-step explanation:

a/(2x-c) = -1

The first step is to multiply both sides by (2x - c)

(2x - c)a/(2x-c) = -1(2x - c)

a = -2x + c

a - c = -2x + c - c

a - c = -2x

Divide both side by -2

(a - c)/-2 = x

∴ x = [tex]\frac{(a - c)}{-2}[/tex]

Step-by-step explanation:

6x+18=h(3x+9)

To have an infinite number of solutions, the left and right side must be equal

Distribute the h

6x+18 = 3xh +9h

6x = 3xh

Divide by x

6x/x = 3xh/x

6 = 3h

Divide by 3

6/3 =3h/3

2 =h

Lets verify

18 = 9h

Divide by 9

18/9 = 9h/9

2 =h

h must be 2

Answer:

z = 7

Step-by-step explanation:

9z + 4 / 5 - 8 = 5.4

Add 8 to both sides.

9z + 4 / 5 = 13.4

Multiply 5 by both sides.

9z + 4 = 67

Subtract 4 from both sides.

9z = 63

Divide both sides by 9.

z = 7

Answer:

7 (rounded up)

Step-by-step explanation:

9z+4/5=13.5

Multiply both sides by 5

9z+4=67.5

Subtract both sides by 4

9z=63.5

Divide both sides by 9

z=7 (rounded up)

Answer: h=14

Step-by-step explanation:

7h-5(3h-8)=-72

7h-15h+40=-72 > I distributed the -5(3h-8) to get rid of parenthesis

-8h+40=-72 > I combined the like terms 7h-15h

-8h=-112 > I subtracted 40 from both sides

h=14 > I divided -8 from both sides

The solution is h = 14.

Given: Equation

7h - 5(3h - 8) = -72

Now, we will solve the equation for the value of h.

⇒ 7h - 5(3h - 8) = -72

⇒ 7h - 15h + 40 = -72

⇒ 7h - 15h = -72 - 40

⇒ -8h = -112

Dividing both sides by -8, we get:

⇒ h = 14

Therefore, the solution of the given equation is h = 14.

Answer:

48 tickets

Step-by-step explanation:

I just had this question on a test and got it right! So this is how i did it:

if the advance price is $4, and you sell 40 tickets in advance, you do 40 times 4.

40 x 4 = 160

so you subtract the $160 from 400 and then that brings you $240 dollars left.

*these 240 dollars will be tickets bought at the door*

to determine the amount of tickets that need to be bought left, you need to do 240 divided by 5.

and that will give you a total of:

a least amount of 48 tickets

The least number of tickets the club needs to sell at the door to reach the president’s goal, 48.

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given that, Tickets to a play cost $4 in advance and $5 at the door. The theater club president wants to raise at least $400 from the ticket sales. If the club sells 40 tickets in advance,

Since, the cost if advance ticket is $4 and they already sold 40,

Therefore, collected cost = 4 × 40 = $160

Now, cost to collect yet = 400 - 160 = $240

Cost of tickets at the door = $5

Therefore, tickets to be sold to meet the goal = 240/5 = 48

Hence, the least number of tickets the club needs to sell at the door to reach the president’s goal, 48.

Answer:

y = 5x + 29

Step-by-step explanation:

y=5x+2

Given equation is in the form of y=mx+b

Where m is the slope = 5

and b is the y intercept = 2

When the lines are parallel then their slopes are equal

So the slope of parallel line is also 5 (m=5)

Given that the line passes through (-6,-1)

We use point slope formula

y-y1= m (x-x1)

m=5, x1= -6, y1=-1

Plug in all the values

y - (-1) = 5(x-(-6))

y + 1= 5 (x+6)

y + 1= 5x + 30

Subtract 1 on both sides

y = 5x + 29
