Question

A. Step 1B. Step 2 C. Step 3D. Timothy did not make a mistake

Answer 1

Answer: the image isn't showing up for me

Explanation:

Answer 2

We would have to solve the equation

`9(2x+(1)/(3))=39`

Step by step to determine if Timothy made a mistake.

Step 1

Expand the bracket

`\begin{gathered} (9*2x)\text{ +(9}*(1)/(3))=39 \\ 18x+3\text{ = 39} \end{gathered}`

Hence, his step 1 is correct.

Step 2

Bring like terms together

`\begin{gathered} 18x=39-3 \\ 18x=36 \end{gathered}`

Step 3

Simplify step 2 and find the value of x

`\begin{gathered} (18x)/(18)=(36)/(18) \\ x=2 \end{gathered}`

Hence, from all the steps through 1 to 3, we can conclude that Timothy did not make a mistake. Hence the right answer is option D
