PLEASE HELP QUICK
Celia uses the steps below to solve the equation -3/8(-8-16d)+2d=24



Step 1 Distribute -3/8 over the expression in parentheses.


3-16d+2d=24

Step 2 Simplify like terms.

3-14d=24


Step 3 Subtract 3 from both sides of the equation.

-14d=21

Step 4 Divide both sides of the equation by –14.

d=21/-14=-3/2=-1 1/2


Which corrects the error in the step in which Celia made the first error?

In step 1, she should have also distributed -3/8 over 2d, to get 3-16d+(-3/4d)=24.
In step 1, she should have also distributed -3/8 over –16d, to get 3+6d+2d=24. In step 3, she should have added 3 to both sides of the equation to get -14d=27.
In step 3, she should have first divided both sides by –14 to get 3+d=24 .

➷ First, just divide the numbers:

12/4 = 3

When dividing values with exponents, you have to subtract the exponents:

7 - 5 = 2

Therefore, your answer would be option B. 3b^2

Answer:

Step-by-step explanation:

I am assuming that you meant the following:

 12b^7

------------

  4b^5

Note that " ^ " is the proper symbol for exponentiation, and " * " for multiplication.

12/4 = 3 and b^7 / b^5 = b^2.  Thus,

 12b^7

------------ = 3b^2 (or, better yet, 3b²).

  4b^5

Final answer:

To find f(8) for f(x) = 2x - 7, plug 8 into the equation and simplify: f(8) = 2(8) - 7, which equals 9.

Explanation:

To find the value of the function f(x) at x = 8, you simply substitute the value of 8 into the function. Given f(x) = 2x - 7, substituting 8 for x gives us:

f(8) = 2(8) - 7

Now, multiply 2 by 8:

f(8) = 16 - 7

Then, subtract 7 from 16:

f(8) = 9

Therefore, the value of the function f(x) when x = 8 is 9.

Answer:

Sara has 24-x-7

Tim has 24+x/2

Explanation:

So for Tim, He had 24 and received x no of sweets from Sara, so

24+x

After that, he ate half of it, so

24+x/2

Now for Sara, She had 24 and gave Tim x no of sweets, so

24-x

After that, she ate 7 of it, so

24-x-7

Hope it helps

The expression for the number of sweets Sara and Tim have now after sharing and eating some is represented as 29 - 0.5x.

Expression for the number of sweets Sara and Tim have now:

Sara gives Tim x sweets, so Sara has 24 - x sweets and Tim has 24 + x sweets.

After Sara eats 7 of her sweets, she has 24 - x - 7 = 17 - x sweets left.

Tim eats half of his sweets, so he has (24 + x) / 2 = 12 + 0.5x sweets left.

The total number of sweets Sara and Tim have now is: (17 - x) + (12 + 0.5x) = 29 - 0.5x.

the answer is y=3x-1

the 3 comes from the point moving 3 up and 1 right and the -1 comes from the y intercept

Answer:

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y = mx + b

m - slope

b - y-intercept

From the graph we have the y-intercept: (0, -1). Therefore b = -1.

y = mx - 1

From the graph we have the second point (1, 2). Put the coordinates of this point to the eqution:

2 = m(1) - 1

2 = m - 1               add 1 to both sides

3 = m

Finally we have

y = 3x - 1

(3+√2)(3-√2) =  7

Step-by-step explanation:

We have given a expression.

(3+√2)(3-√2)

We have to simplify above expression.

We use difference formula to solve above expression.

(a-b)(a+b) =   a²-b²

(3+√2)(3-√2) =  (3)²-(√2)²

(3+√2)(3-√2) =  9-2

(3+√2)(3-√2) =  7 which is the answer.

Your answer is 5 gallons

Answer:

5

Step-by-step explanation:

1/4 has 3 x's, so we multiply 1/4 by 3 to get 3/4.  3/8 has 2 x's so we multiply 3/8 with 2 to get 3/4.  5/8 has 4 x's, so we multiply 5/8 by 4 to get 10/4.  1 has 1 x so we multiply 1 with 1 to get 1.  Adding these up, we get 3/4 + 3/4 + 10/4 + 1 = 16/4 + 1 = 5.

Answer:

Choose the best estimate for the capacity of a bath tub

A. 5 ml

B. 500 ml

C. 50 cl

D. 500 L

Step-by-step explanation:

The best estimate for the capacity of a bathtub is 500 Liters (500L) as it provides a measure that is comparably similar to the actual volume of a bathtub.

The best estimate for the capacity of a bathtub would be  500 Liters (500L). This is because the capacity of a bathtub is usually much larger than a litre. Option A and B provide measurements in millilitres, which are much smaller units (a liter is 1,000 millilitres), and thus would not be sufficient to measure a bathtub's capacity. Option C is calling for centilitres, where 1 centilitre is equivalent to 10 millilitres, still way smaller than a bathtub's capacity. Hence, 500L (500 Litres) is the most reasonable estimation for the capacity of a bathtub.

Option A. 1 mile per minute.

Step-by-step explanation:

Brandon has traveled after the specified period of time. The table shows his covered distance in a specific time.

Minutes    0     5     10     15     20     25

Miles         0    3      7      12      17      21

In this question we have to calculate speed per minute in between 15 and 20 minutes.

As we can see in the table from 15 to 20 minutes, he traveled :

17 - 12 = 5 miles  Time taken = 20 - 15 = 5 minutes

Speed = [tex]\frac{distance}{time}[/tex]

S =  [tex]\frac{5}{5}[/tex] = 1 mile per minute.

Option A) 1 mile per minute

if the die has six sides, the probability that he will roll 2 again is 1/6 since there’s only one 2 out of the six sides

The probability jack will get 2 on the next roll is 1/6.

It is the ratio that determines how likely a certain event can occur within a set of possible events.

The given dice has 6 sides.

The number 2 occurs only on one side of a die.

Therefore, if he were to roll the dice one more time, the probability that he would get 2 can be given by 1/6.

Therefore, the probability that jack will get 2 on the next roll is 1/6.

The surface area of prism = 81 ft²

Step-by-step explanation:

∵ The triangular prism has 5 faces

- Two triangles ⇒ bases

- 3 rectangles ⇒ side faces

* to find the surface area of it, we will find the area of

 each face and add them together

- Area of bases:

∵ The bases are right angle triangles with base 6 ft and height 4.5 ft

∵ Area triangle = 1/2 × base × height

∴ Area one base = 1/2 × 6 × 4.5 = 13.5 ft²

∴ Area two bases = 13.5 × 2 = 27 ft² ⇒ (1)

- Area of the first rectangle with dimensions 3 ft and 6 ft

∵ Area rectangle = L × W

∴ Area 1st rectangle = 3 × 6 = 18 ft² ⇒ (2)

- Area of the second rectangle with dimensions 3 ft and 7.5 ft

∴ Area 2nd rectangle = 3 × 7.5 = 22.5 ft² ⇒ (3)

- Area of the third rectangle with dimensions 3 ft and 4.5 ft

∴ Area 3rd rectangle = 3 × 4.5 = 13.5 ft² ⇒ (4)

Add (1) , (2) , (3) and (4)

∴ The surface area of prism = 27 + 18 + 22.5 + 13.5 = 81 ft²

Answer:

81

Step-by-step explanation:

you are right, but remember since the base is an actual number then you need to raise 5 to the power of 4. Your answer is 625.

[tex]\bf \begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\\\ x&-\frac{3\pi }{10} \end{array}\implies \cfrac{180}{x}=\cfrac{\pi }{~~-\frac{3\pi }{10}~~}\implies \cfrac{180}{x}=\cfrac{\frac{\pi}{1} }{~~-\frac{3\pi }{10}~~} \\\\\\ \cfrac{180}{x}=\cfrac{\pi }{1}\cdot \cfrac{10}{-3\pi }\implies \cfrac{180}{x}=-\cfrac{10}{3}\implies 540=-10x\implies \cfrac{540}{-10}=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill -54=x~\hfill[/tex]

Answer:

1-ELIMINATION.

2- SUBSTITUTION.

3- GRAPHING.

Step-by-step explanation:

Methods:

1- Elimination:

- Line up the variables.

- To cancel out one of the variables, you need to make that the coefficient of that variable opposite. For example:

[tex]\left \{ {{3x+y=1} \atop {-3x+4y=3}} \right.[/tex]

As you can see, the coefficient of x in the first eqation is 3 and -3 in the second option.

- Add the equations.

- Solve for the the variable that is still present.

- Substitute the value of the variable obtained into one of the original equations.

- Solve for the other variable.

2- Substitution:

- Solve for one of the variables from any of the equations of the system.

- Substitute into the other equation for that variable.

- Solve for the other varible to find its value.

- Substitute the value obtained into any of the original equations and solve for the other variable.

3- Graphing:

- Rewrite the equations as equtions of the line slope intercept form ([tex]y=mx+b[/tex], where m is the slope nd b the y-intercept).

- Graph each line.

-  Then:

If there ir an intersection point of the two lines, then that point is the solution to the system

If the lines are the same, there are infinitely many  solutions.

If the lines are parallel, then there is no solution

Answer: A

put x = 3 into f(x)=6x and you get f(x) = 18

Put x = 4 into f(x) and you get f(x) = 24

Subtract those two. 24 - 18 = 6

Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.

Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,

6(x+1) = 6x + 6.

+6, it increases.

[tex]f(4)=\frac{4}{3}[/tex]

Evaluating a function means substituting the variable (x in this case) by the given value (4 in this case), so where is an "x" we should rewrite with the number 4.

So, evaluating the function for [tex]x=4[/tex] we have:

[tex]f(4)=\frac{1}{3}(4)=\frac{1}{3}*4=\frac{4}{3}[/tex]

Have a nice day!

Answer: [tex]f(4)=\frac{4}{3}[/tex]

Step-by-step explanation:

To solve the problem shown above, you only need to substitute x=4 into the given fucntion.

By definition, the value of x (which is this case is 4) is  called the input value and the value obtained when you susbtitute it into the function is called the output value.

Keeping the above on mind when you susbtitute x=4 into the function,  you obtain the  result shown below:

[tex]f(x)=\frac{1}{3}x\\\\f(4)=\frac{1}{3}(4)\\\\f(4)=\frac{4}{3}[/tex]
