Question

Solve this inequality: 3b – 7 < 32

A. b < 39
B. b < 13
C. b < 8.33
D. b < 5

Answer 1

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.

Answer 2

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.
