Set up a proportion do so for X in the following similar triangles

x = 64

Step-by-step explanation:

The triangles are similar, so we'll set up a proportion:

=>

Cross Multiplying

=> 2(x-4) = 15 x 8

=> 2x-8 = 120

=> 2x = 120+8

=> 2x = 128

Dividing both sides by 2

=> x = 64

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
