Solve this inequality: 3b - 7 < 32

A. b < 39

B. b < 13

C. b < 8.33

D. b < 5

The answer is B, because if it were 13, the equation would be 39-7<32, which is not true, so it is less than 13, and therefore the answer is B.

Hello! So for this question, we need to get the number with the variable by itself. First, let's add 7 to cancel out - 7. Add 7 to 32 to get 39. Then, we get 3b < 39. Now, divide each side by 3 to isolate the b. 39/3 is 13. There. b < 13. The answer is B.
