mr.masons height is at most 4 inches more than twice his daughters height.Mr.masons height is 70 inches

Answer 1

4h - 6 = 70
4h = 70 + 6
5 = 76/4 = 19
So.... 19 inches.

Answer 2

M < = 2d + 4
m = 70

70 < = 2d + 4
70 - 4 < = 2d
66 < = 2d
66/2 < = d
33 < = d...or d > = 33

so the daughter is at least 33 inches
