6A barrel holds 21 qt of oil. Trina drains the barrel at a rate of 6 c per min. How long does it take her to empty the barrel? Show your work. (1 qt = 4 c )

14 minutes

Step-by-step explanation:

The barrel held 21 quarts of oil, which is equal to 84 cups. Trina drains the barrel at 6 cups per minute, so to find out how much time it takes her to drain it, divide 84 by 6:

84 / 6 = 14

So, it took Trina 14 minutes to drain the whole barrel.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

according to egenuity the answer is
