Answer:

  • C. 3(b - 2) = 24

Step-by-step explanation:

b = 10

Substitute b in every equation below and compare the results

A. 2(b + 4) = 16

  • 2(10 + 4) = 2(14) = 28 ≠ 16, incorrect

B.  2(b + 2) = 40

  • 2(10 + 2) = 2(12) = 24 ≠ 40, incorrect

C. 3(b - 2) = 24

  • 3(10 - 2) = 3(8) = 24, correct

D. 2(8 + b) = 42

  • 2(8 + 10) = 2(18) = 36 ≠ 42, incorrect

E. 3(b - 4) = 20

  • 3(10 - 4) = 3(6) = 18 ≠ 20, incorrect

Answer:

C. 3(b - 2) = 24..
