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 $\frac{2x}{3} - 9$

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

$\frac{2x}{3} - 9$

= $\frac{(2 \times -6)}{3} - 9$

= $\frac{(-12)}{3} - 9$

= $-4 - 9$

= -13

So, the value of the expression is -13.
