PLEASE HELP!!!

Answer:1) 52

2) 9

3) 4

4) 12.5

5) 112

Step-by-step explanation:So for each of them, we just need to substitute and solve.

4n = 4 * 13 = 52

a/b = 27/3 = 9

3x – 14 = 3*6 – 14 = 18 – 14 = 4

z2 + 8.5 = 2*2 + 8.5 = 4 + 8.5 = 12.5

x(36 – y) = 4(36 – 8) = 4(28) = 112

I hope this helped and please mark brainliest!
