You can put this solution on YOUR website! V=L*W*H
V= 58.66*18.5*.75
= approx 814 cubic feet
which rounds out to 30 cubic yards, 814/27 = approx 30.
You can put this solution on YOUR website! 5-2/x-6=10-2x/x-6
5-2/x=10-2x/x add 6 to both sides
-2/x=5-2x/x minus 5 from both sides
-2=5x-2x multiply bs by x
-2=3x
x=-2/3
