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.

answer: ouch. thats difficult

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
