AC = 20

Step-by-step explanation:

Given

AC = 9x+2\\BC = 5x+1\\AB = 9

B is between A and C so,

AC = AB+BC\\9x+2 = 9 + 5x+1\\9x+2 = 5x+10\\9x +2-5x = 10 \\4x +2-2 = 10-2\\4x = 8

Dividing both sides by 4

\frac{4x}{4} = \frac{8}{4}\\x = 2

Putting x=2 in AC

AC = 9(2)+2\\= 18+2\\= 20

Hence,

AC = 20
