John bought a quart of ice-cream for $4.80. How much does the ice-cream cost per cup? 1 guart = 4 cups

each cup is $1.20 each

Step-by-step explanation:

Y = 24

∠7 = 89°

∠8 = 89°

Getting Y:

Due to vertical angles, we know that both equations are equal to each other, so we can set them equal to each other to find Y!

STEP 1: 5y-29=3y+19

DO: Add 29 to both sides to get y alone.

STEP 2: 5y=3y+48

DO: Subtract 3y from both sides to get y by itself again.

STEP 3: 2y=48

DO: Divide by 2 from both sides to get y alone for the last time!

STEP 4: y=24

You found Y! It's all about isolating that variable.

STEP 5: Plug 24 into both equations, and solve. You should get 91 for both. Now the last part is easy.

REMEMBER: Both angles next to each other must equal to 180, so now that we know one of the sides is equal to 91, we simply subtract 91 from 180, to get 89 as our answer for ∠7. Since ∠7 is a vertical angle to ∠8, we know they are the same!

I truthfully hope this helped you! :D
