Answer:
56
Step-by-step explanation:
We are given the expression:
10y-3z
and asked to find the value when y=8 and z=8. Therefore, we must substitute 8 in for both y and z.
10(8)-3(8)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition and Subtraction.
Multiply 10 and 8.
(10*8) -3(8)
80-3(8)
Multiply 3 and 8.
80 - (3*8)
80- 24
Subtract 24 from 80.
(80-24)
56
The value of the expression 10y-3z when y=8 and z=8 is 56.
