Square root is 220 the number is way bigger than 14 3/4
21ft in yards equals 7 yards I hoped this helped!
-x + 2y = 6 then x = 2y - 6
6y = x +18 then x = 6y - 18
-----------------------substract
0 = -4y + 12
4y = 12
y = 3
-x + 2y = 6
-x + 2(3) = 6
-x = 6 - 6
x = 0
answer: x = 0 (second choice)

Answer:
It will take 18 minutes to fill the trough using both pumps.
