X+y=120 5.25x+3.0y=517.2

Sauron [17]

I will try to solve your system of equations.
x+y=120;5.25x+3y=517.2
Step: Solvex+y=120for x:
x+y+−y=120+−y(Add -y to both sides)x=−y+120
Step: Substitute−y+120forxin5.25x+3y=517.2:
5.25x+3y=517.25.25(−y+120)+3y=517.2−2.25y+630=517.2(Simplify both sides of the equation)−2.25y+630+−630=517.2+−630(Add -630 to both sides)−2.25y=−112.8−2.25y−2.25=−112.8−2.25(Divide both sides by -2.25)y=50.133333
Step: Substitute50.133333foryinx=−y+120:
x=−y+120x=−50.133333+120x=69.866667(Simplify both sides of the equation)
Answer:
x=69.866667 and y=50.133333

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 16,111 gallons of water, and is leaking at a rat

Lera25 [3.4K]

Answer:

There are 15,112 gallons of water will remaining in the pool ⇒ answer D

Step-by-step explanation:

* Lets explain how to solve the problem

- The rate is the ratio between two related quantities in different units

- The pool is leaking slowly at rate 9 gallons per second that means the

quantity of the water in the pool decreased 9 gallons each day

- The find the remaining gallons in the pool after 111 days, find the

amount of water has leaked from the pool in these days

∵ The rate of leaking is 9 gallons per day

∵ Mike does not replace the water that has leaked from the pool

- The amount of water leaked in some days = the rate of leaking

× the number of days

∵ The number of days is 111 days

∵ The amount of water lacked = 9 × 111 = 999 gallons

∵ The amount of water remaining in the pool after some days =

the total amount in the pool - the amount of leaked in that days

∵ The pool holds 16,111 gallons of water

∴ The amount of water remaining = 16111 - 999 = 15112 gallons

* There are 15,112 gallons of water will remaining in the pool
