Answer 1

3) D. 11 3/5
4) C. 18
5) D. 5/12 feet

Answer 2

3) b= 11 3/5

4) n= 1/18

5) 5/12 feet

Explanation:

3) add -3 2/5 to both sides

4) multiply both sides by 3n, divide by -42, then divide 7/42 by 3 (or multiply it by the reciprocal: 1/3)

5) convert the height to inches by multiplying by 12, subtract 69 from 74, then divide answer by 12
