The local school sponsored a mini-marathon and supplied 84 gallons of water per hour for the runners. What is the amount of wate

Dmitrij [34]

All you need to do is multiply 84 by 4.

The number of gallons by the number of quarts in a gallon. 

80*4= 320

4*4=16

320+16= 336

There are 336 quarts of water supplied an hour.

I hope this helps!

True

Step-by-step explanation:

The question is asking if the number square below is -3. We found out from above that is -3 so it's true.
