A faucet leaks water at a constant rate of quart every 15 minutes.

How many quarts does the faucet leak per hour?

An hour is 60 minutes.

60 minutes/ 15 minutes = 4

There are 4 15 minute segments in an hour.

1 quart x 4 = 4 quarts per hour.

4 quarts per hour.

Step-by-step explanation:

60/15 = 4

The reason why i did 60 is because there is 60 min in a hour. then i divided it by 15 and got 4

hope this helps : )

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
