Shauna is 10 inches shorter than ryan. together their heights total 140 inches. how tall is each person?

Shauna is 65 inches tall and Ryan is 75 inches tall.

Let the height of:

Shauna be represented with s

Ryan be represented with r.

Sum of their heights : s + r = 140

The equation that represents Shauna's height : r - 10

Substitute for Shauna's height in the first equation:

r - 10 + r = 140

Solve for r

2r = 150

r = 75 inches

Substitute for r in the first equation

75 + s = 140

s = 140 - 75

s = 65 inches
