A pool is being drained at a rate of 120 gallons per minute.What is this rate in quarts per hour?

1 answer:

7 0

There are 4 quarts in 1 gallon, so a rate of 120 gallons per minute converts to 4 x 120 = 480 quarts per minute. To find the per hour rate, we simply multiply our per minute rate by 60, obtaining 480 x 60 = 28800 quarts per hour.

Solve the literal equation for y. 4x-5=7+4y

Natalka [10]

Answer:

y=x−3

Step-by-step explanation:

Flip the equation.

4y+7=4x−5

Add -7 to both sides.

4y+7+−7=4x−5+−7

4y=4x−12

Divide both sides by 4.

$\frac{4y}{4}= \frac{4x-12}{4}$

y=x−3

ik this doesnt make any sense but hope this helps :/
