Answer:

The rate is 0.9 gallon per minute

Step-by-step explanation:

Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute

Let the amount drained per minute be x

4.5 gallons = 5 minutes

x gallon = 1 minute

Let’s cross multiply;

x * 5 = 4.5 * 1

5x = 4.5

x = 4.5/5

x = 0.9 gallons

A student's tuition was $3000. A loan was obtained for 5/6 of the tuition. How much was the loan?
Marina86 [1]
Answer: 2,500

5/7 of 3500 = (5/7)*(3500)

5/7 of 3500 = (5/7)*(3500/1)

5/7 of 3500 = (5*3500)/(7*1)

5/7 of 3500 = (17500)/(7)

5/7 of 3500 = 2500

PLEASE HELP! DUE AT 11:59 PST
Nesterboy [21]

Answer:

Y = 15x + 30 and 8 hours

Step-by-step explanation:

She gets $15 per hour so her income is based on her hours, but we don't know what that is yet so, 15x.

She gets a solid $30 every week that is straight forward

To solve the function

150 = 15x + 30

subtract 30 from both sides

120 = 15x

divide 15 from both sides

8 = x

or

x = 8

You got this :)
