Answer:
Russell family's sprinkler: 40 hours
Gonzales family's sprinkler: 20 hours
Step-by-step explanation:
Let's call the amount of time the Russell family's sprinkler was on by X, and the Gonzales family's sprinkler by Y.
We can then formulate the equations:
X + Y = 60
X*35 + Y*40 = 2200
We can solve this system multiplying the first equation by 35, and then subtracting the result from the second equation:
35*X + 35*Y = 2100
5*Y = 100
Y = 20
from the first equation:
X + 20 = 60
X = 40
Russell family's sprinkler: 40 hours
Gonzales family's sprinkler: 20 hours

Answer:
5/9 cubic yards
Step-by-step explanation:
Just so L*W*H=24(36)(30)= 25920 cubic inches=25920 (1 in*1 in* 1 in)
36 in=1 yd
so
1 in =1/36 yd
do divide 25920 by (36*36*36)
The answer in cubic yards is 5/9 cubic yards
It would be 2x/3y assuming that’s meant to say 15y^2
