Question

Kellen solved 9 + 5m = 17 and got m = 1.6. Is he correct?
Option 1: Yes
Option 2: No

Answer 1

Our answer is: m = 1.6.

`\Large\textsf{\textbf{Explanation}}`

We are asked to solve the following equation for m -

`\boldsymbol{9+5m=17}`

Start by subtracting 9 from both sides:

5m = 17 - 9

5m = 8

Divide both sides by 5:

m = 1.6

`\therefore` m = 1.6; Kellen is correct.

Answer 2

option 1 : Yes

Explanation:

given the equation

9 + 5m = 17 ( subtract 9 from both sides )

9 - 9 + 5m = 17 - 9 ( simplify both sides )

5m = 8 ( divide both sides by 5 )

`(5)/(5)` m =
`(8)/(5)` , that is

m = 1.6
