Grade 9 Math Algebra 1 Variables & Expressions

Can anyone help me with this question?

Write an expression and then evaluate when x = -6.

Nine subtracted from the quotient of twice a number, x, and three. ?

Evaluate when x = -6 ?

Answer 1

We have to determine the expression for the statement:

"Nine subtracted from the quotient of twice a number, x, and three"

Expression is
`(2x)/(3) - 9`

We have to evaluate the value of the given expression at x = -6

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

=
`((2 * -6))/(3) - 9`

=
`((-12))/(3) - 9`

=
`-4 - 9`

= -13

So, the value of the expression is -13.
