A hose fills a hot tub at a rate of 3.47 gallons per minute. How many hours will it take to fill a 334-gallon hot tub?​

1.6

Step-by-step explanation: To find how many gallons it is in 1 hout you take 3.47*60 for one hour. That equals 208.2. Then you take 334 and divide it by 208.2. then round to the nearest hundreth.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
