1) 2x/6 = 24/8
2) 2/3x = 36/12
3) The two triangles are similar solve for the missing side. Set up an proportion.
5 ---------------- --------------------------- x
13 20
4) A tree casts a shadow 8-ft long. A 6-ft tall man casts a shadow of 4-ft. long. How tall is the tree? Set up a proportion.
5) A new Flat Screen TV that regularly sells at $800 was on sale at 60% discount. Which equation can be used to find the sale price? Solve the equation to find the sale price.
A) x = 800 - 0.60(800)
B) x = 800 + 0.60(800)
C) x = 800 - 0.40(800)
D) x = 800 + 0.40(800)
Help me do them and show all steps!!! I will choose your answer as the best if you show all steps, and the answers :) Thanks!!

I can only give you the first two.
If you cross multiply and set them equal to each other, 1) would look like 16x=144. Then solve for x and x=9
2) same deal except you can simplify the 36/12.
9x=2
x=2/9
hope you can get the rest. good luck
