Question

Evaluate 3z- 3 when z=7

a 34
b 21
c 18

Answer 1

Answer: C (18)

Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.

Answer 2

Answer:

C

Step-by-step explanation:

Since z = 7 the equation would be 3(7) - 3

You would multiply 3 with 7 and get 21

Then you would subtract 3 from 21 and get 18

hope this helps.
