I got c which is 100 but I don’t know how jerry got A

Choice C is the correct answer because

\frac{(6+2)^3-12}{5}\\\\\frac{(8)^3-12}{5}\\\\\frac{512-12}{5}\\\\\frac{500}{5}\\\\100\\\\

So in short, \frac{(6+2)^3-12}{5}=100\\\\

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

The mistake Jerry likely made was that he only cubed the 2 and didn't realize the 6 was part of that cubing process. It seems he didn't add first and decided to cube before adding.

This is probably what steps Jerry did

\frac{6+2^3-12}{5}\\\\\frac{6+8-12}{5}\\\\\frac{14-12}{5}\\\\\frac{2}{5}\\\\

But as mentioned, those steps are incorrect because the 6 is part of the cubing operation. In other words, Jerry should have added the 6+2 first before cubing afterward (due to PEMDAS determining the order of operations).

Or you could think of it like this

\frac{(6+2)^3-12}{5}\\\\\frac{(6+2)(6+2)(6+2)-12}{5}\\\\\frac{(8)(8)(8)-12}{5}\\\\\frac{512-12}{5}\\\\\frac{500}{5}\\\\100

Answer:

\large \boxed{69^{\circ}}

Step-by-step explanation:  

                  Let y = m∠Y.

       Then 90 - y = the complement of ∠Y

     And 3(90 - y) = three times the complement of ∠Y

And 3(90 - y) + 6 = six more than three times the complement of ∠Y.

\begin{array}{rcll}y & = & 3(90 - y) + 6 & \\& = & 270 - 3y + 6 & \text{Distribuetd the 3}\\& = & 276 - 3y & \text{Simplified}\\4y &= & 276 & \text{Added 3y to each side}\\y & = & \mathbf{69} & \text{Divided each side by 4}\\\end{array}\\m \angle Y = \large \boxed{\mathbf{69^{\circ}}}

Question:

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. what is the unit rate at which Martian paints in walls per gallon

Answer:

0.78125  walls per gallon

<em></em>

Step-by-step explanation:

Given

Paint = \frac{5}{8}\ gallon

Wall = \frac{4}{5}

Required

Determine the unit rate

This is calculated as:

Unit\ Rate = \frac{Wall}{Paint}

Substitute values for wall and paint

Unit\ Rate = \frac{5/8}{4/5}

Simplify:

Unit\ Rate = \frac{5}{8}/\frac{4}{5}

Change to *

Unit\ Rate = \frac{5}{8}*\frac{5}{4}

Unit\ Rate = \frac{5*5}{8*4}

Unit\ Rate = \frac{25}{32}

Unit\ Rate = 0.78125

<em>Hence, the unit rate is: 0.78125  walls per gallon</em>

Describe and correct the error in the solution. (Be specific and explain as
sweet [91]
The error occurred in step 2. You have to use the distributive property for the parenthesis. It is supposed to be 5p+15.

The correct solution is p>-13.
