Examine the first two steps used to solve the equation. 3
4
(20y − 8) + 5 = 1
2
y + 1
4
(20y + 8)

1. 15y − 6 + 5 = 1
2
y + 5y + 2

2. 15y − 1 = 11
2
y + 2

Which would be a good third step to solve the equation?
Combine like terms StartFraction 11 Over 2 EndFractiony and 2.

Distribute 15 to each term on the left side.
Subtract StartFraction 11 Over 2 EndFractiony from each side of the equation.
Divide each side of the equation by 2.

hope your goes well, here's a turkey

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
