A standard bathtub holds 70 gallons of water. On average, it takes 7 and 1/2 minutes to drain a bathtub. How many gallons of water go down the drain each minute?​

9 gallons of water

Step-by-step explanation:

To find how many gallons of water go down each minute, divide the total number of gallons of water by the number of minutes it takes to drain:

70/7.5

= 9

So, 9 gallons of water go down the drain each minute

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
