4.) Find the Missing Length 4.) 5/30 = x/120 120 x 30 5

Bellwork 4/6 Solve 1.) x/4 = 27/36 36x = 108 x = 3

Bellwork 4/6 Solve 2.) 5/x = 27/30 27x = 150 x = 150/27 = 50/9

3.) (x+6)/(x-2) = 2/x x2 + 6x = 2x - 4 x2 + 4x + 4 = 0 Bellwork 4/6 Solve 3.) (x+6)/(x-2) = 2/x x2 + 6x = 2x - 4 x2 + 4x + 4 = 0 (x + 2)(x + 2) = 0 x = -2

Find the Missing Length 5/30 = x/120 30x = 600 x = 20 120 x 30 5
