Question

Kesley is thinking of a number. She says that it’s the sum of a number and nine. Multiplied by 2/3, is equal to -18.

Answer 1

Only the firsts and fourth choices (
`(2)/(3)(x+9)=-18` and
`(2)/(3)x+6=-18`)

Explanation:

Turn the equation into words:

"A number plus 9"

`(x+9)`

"Multiplied by
`(2)/(3)`"

`(2)/(3) (x+9)`

"Is equals to -18"

`(2)/(3)(x+9)=-18`

Distribute to find the second equation:

`(2)/(3)(x+9)=-18\\(2)/(3)x+6=-18`
