The height of a poster is 7x+10 and its perimeter is 20x+24. What is the width of the poster?

Width = 3x + 2

Step-by-step explanation:

Given:

Height = 7x + 10

Perimeter = 20x + 24

Let the width of the poster be W

Assuming that the poster is rectangular, then:

Perimeter = 2 (Height)  + 2 (Width)

Substituting the values above:

20x + 24 = 2(7x+10) + 2W

20x + 24 = 14x+20 + 2W  (subtract 14x + 20 from both sides)

20x + 24 - (14x+20)=  2W

20x + 24 - 14x - 20=  2W

6x + 4 = 2W   (divide both sides by 2 and rearrange)

W = (6x+4)/2 = 3x+2

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

y/x of point b= y/x of point a
