Question

Evaluate the expression 9b−6b÷3b for b=7.

Answer 1

I'm not sure which one it is, so I did both.

1. 9b-(6b/3b) = 9b-2

b = 7

9(7)-2 = 61

2. (9b-6b)/3b = 1

Answer 2

The answer is 1.

Explanation:

9 times 7 equals 63. 6 times 7 equals 42. 3 times 7 equals 21.

63 take away 42 is 21.

21 divided by 21 is 1!
