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

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
