Question

The product of 8 and the quantity 9 less than c is less than 13

Answer 1

8(c - 9) < 13

First, distribute 8 to all terms within the parenthesis

8(c - 9) = 8c - 72

8c - 72 < 13

Next, isolate the c. Do the opposite of PEMDAS. Add 72 to both sides

8c - 72 (+72) < 13 (+72)

8c < 85

Divide 8 from both sides

8c/8 < 85/8

c < 85/8

c < 10.625

c < 10.625 is your answer

hope this helps
