You need to solve the equation for h.
<span>W= 50+2.3(h-60)
Distribute the 2.3.
W = 50 + 2.3h - 138
W = 2.3h - 88
Add 88 to both sides.
W + 88 = 2.3h
Switch sides.
2.3h = W + 88
Divide both sides by 2.3.
h = (W + 88)/2.3

There are 12! ways to line 12 people up. That is 12 factorial (the name for the exclamation point
12! means 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Using a scientific calculator to compute 12!, we get 479,001,600 ways to line up 12 people. I know it sounds amazing but here is a chart.
People Ways
3 6
4 24 (Notice that if you multiply 6 x 4 you get 24)
5 120 (Notice that if you muliply 24 x 5 you get 120 etc.)
6 720
7 5040
8 40,320
9 362,880
10 3,628,880
11 39,916,800
12 479,001,600
your answer is -1/100 (a fraction)
5*3+2=17 it's A, 3 in this equation.
