2(2x+9) = 8x - 50 2x+9 = 4x - 25 2x = 36 x = 18 AM = 2x + 9 = 2(18) + 9 = 45 <<< answer

AM would be half of AB, so: (8x - 50) / 2 = 2x + 9 Now we can solve for x: 4x - 25 = 2x + 9 2x = 34 x = 17 Now that we have x, we can solve for the length of AM: 2x + 9 2(17) + 9 34 + 9 43 units

2x+9=8x-50=> 6x=59=> x=59/6=> AM=2(59/6)+9=> AM=28.6667 approximately
