Question

If AC=13x-17, find x. Round your answer to the nearest tenth if necessary AB= 2x+4 BC= 19

Answer 1

x=3.7

1) Given that AC is the line segment made up by AB + BC We can set this equation:

AC=AB+BC

13x-17=2x+4+19 Combining like terms

13x-2x -17=2x-2x+23

11x -17=23

11x -17+17 = 23 +17

11x = 40 Dividing both sides by 11

x=3.63 Round to the nearest tenth

x=3.7
