The perimeter of a rectangle is 20 units. if the width is 3/4 of the way what is the width of the rectangle

W = 4.3 units

Step-by-step explanation:

This rectangle has a perimeter of 20 units. Its width is 3/4 of the way assuming it means 3/4 of the length then w = 3/4 l and the length is l. We can add these expressions together and set it equal to the perimeter then solve for l.

P = l + l + w + w

20 = l + l + 3/4l + 3/4l

20 = 3 2/4 l

20 = 3 1/2 l or 20 = 3.5l

l = 5.7

This means the width will be w = 3/4 l = 3/4(5.7) = 0.75(5.7) = 4.3

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
