What is the value of the expression below when y = 8 and z = 9?
5y – 2z

Answers

Answer:

\boxed {\tt 22}

Step-by-step explanation:

We are given the expression:

5y-2z

We want to find the value of the expression when y=8 and z=9. Therefore, we must substitute 8 in for y and 9 in for z.

5(8)-2(9)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Multiply 5 and 8.

40-2(9)

Multiply 2 and 9.

40-18

Subtract 18 from 40.

22

The value of the expression 5y-2z at y=8 and z=9 is 22.
