A standard showerhead in Sonia's house dispenses 12 gallons of water per minute. Sonia changed this showerhead to an energy-savi
diamong [38]

Sonia saves a lot of water. To figure this out, you plug the number 8 into the equation, replacing it with the variable x. y = 3(8). Therefore, y=24. To find out how much water she saves, you have to also figure out how much water she was using for 8 minutes with the other shower head, the one that wastes the water. Since it dispenses 12 gallons per minute, you multiply that by 8 minutes and get 96. Subtract 24 from 96 and get 72. Which I think is your answer. Then again, I'm in high school so I most likely am wrong.

If 2x = 5y + 3, express y in terms of x.
Slav-nsk [51]

Answer:

y = 2/5 x - 3/5

Step-by-step explanation:

2x = 5y + 3

Rewrite

5y + 3 = 2x

Subtract 3 from both sides

5y = 2x - 3

Divide both sides by 5

y = 2/5 x - 3/5
