Question

Select the correct answer.

Answer 1

Answer:

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

Answer 2

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
