MEDAL!!!!!!!
1. Solve for x.
4(x – b) = x (1 point)
b = 4/3 x
b = 3/4 x
x =4/3 b
x = 3/4 b
2. Solve for y, then find the value of y when given x = –2.
6x = 7 – 4y (1 point)
–12
7/4
19/4
24
3. Solve for h.
A = 1/2bh (1 point)
h= 2a/b
2A =b/h
h = 1/2 Ab
h = 2Ab
4. Find the width of a rectangle with a perimeter of 90 and a length of 15. (1 point)
90
15
45

4(x – b) = x Using distributive property distribute the expression on the left side Then u will get 4*x4*b=x 4x4b=x To solve for x u have to isolate x. to do that follow the steps 1.Add 4b both sides 2.Subtract x both sides 3.Divide by 3 both sides Can u do it @kittykatchan
