You can put this solution on YOUR website! Shoe sizes and foot length are related by the formula S=3F-24, where S represents the shoes size and F represents the length of the foot, in inches.
A. Solve the formula for F
3F = S+24
F = (1/3)S + 8
-----------------------
B. To the nearest tenth of an inch, how long is the foot of a person who wears a size 10 1/2 Shoe?
---
F(10 1/2) = (1/3)(10 1/2) + 8
F(10 1/2) = (1/3)(21/2) + 8
F(10 1/2) = 11 1/2 inches
================================
Solve for x: 2(x-3)= 1.2-x
2x-6 = 1.2-x
3x = 7.2
x = 2.4
================
