use cos to get an equation and then solve.
Answer:
X= - 10
Y=5
Step-by-step explanation:
First add the equations and x will be eliminated, then solve for y as a normal linear function, and the answer is 5.
Substitute thw y in any function, I substituted in the first one, and solved for x and got negative 10 as an answer.
The necessary information's are already given in the question. Based on those information's the answer to the question can be easily determined.
Amount of water recirculated by the pump in 1/5 of an hour = 60 gallons
we already know
1/5 of an hour = (1/5) * 60 minutes
= 12 minutes
Then
Amount of water recirculated by
the pump in 60 minutes = (60/12) * 60 gallons
= 5 * 60 gallons
= 300 gallons
So the amount of water recirculated by the pump per hour is 300 gallons.
