1. At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.

2. How many more minutes will it take for the tank drain completely? Explain or show your reasoning.

3. How many minutes before Jaila arrived was the water tank completely full? Explain or show your reasoning.

Answer 1

Look below

Explanation:

1)= -2/3 per minute decrease by 2 gallons in 3 minutes

2) 5 gallons and lose 2/3 gallons per minute

2/3 gal/minute minutes) = 5 gallons

x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons

3) 10 gallons when full

That is 3 gallons more than the 7 gals there when Jada arrived.

(2/3)(x) = 3

x = 3(3/2) = 9/2 = 4 1/2 minutes

Full= 4 1/2 minutes before she arrived

Happy b-Day!!!!!
