All you have to do is subtract 3/8 from 7 which would give you 9 and 1/3
Divide the perimeter by 2, this will give you the sum of one length and one width.
68/2 = 34 yards
Now the length is 10 yards more, so subtract 10 from the 34 and divide by 2 again:
34 - 10 = 24
24 /2 = 12
The width is 12 yards.
The length is 12 + 10 = 22 yards.
I think the problem is work this way because y is equal to 72 and x is 3 you just multiply 72(3)2=432
18 - 5z + 6z > 3 + 6
18 + z > 9
-18 -18
z > -9
