cuses i dont know what u need

Answer 2

the first question
is y/4=15/20

Answer 3

nevermind i got this one

Answer 4

This would then turn into 20y = 60 if you're still wondering.

Answer 5

We simplify the equation to the form, which is simple to understand
y/4=15/20

Simplifying:
+ 0.25y=15/20

Simplifying:
+ 0.25y=0.75

We move all terms containing y to the left and all other terms to the right.
+ 0.25y=0.75

We simplify left and right side of the equation.
+ 0.25y=0.75

We divide both sides of the equation by 0.25 to get y.
y=3

Answer 6

Answer 10

Do you have multiple choices for your question? I'm not entirely sure if you're looking for a value or an equation.

Answer 11

no

Answer 12

wait

Answer 13

this

Answer 14

Ah, I see now. Alright, I'll be able to calculate that now.

Answer 15

i need explanation

Answer 16

Like previously explained, proportions are set up through cross multiplication and this is no different. Your fractions will turn into 8(z-3) = 30. Of which, you're trying to solve for z.

Answer 17

ok
i got it

Answer 18

Do you need a further explanation?

Answer 19
