Question

What is the value of the expression below when z=5 and w=5?9z−3w

a) 30

b) 15

c) 0

d) 45

Answer 1

The value of the expression 9z-3w when z=5 and w=5 is calculated by substituting the values into the expression, yielding a result of 30.

Step-by-step explanation:

To find the value of the expression 9z−3w when z=5 and w=5, we substitute the values for z and w into the expression:

9(5)−3(5)
= 45 - 15
= 30

Therefore, the value of the expression when z=5 and w=5 is 30.
