A=LxW, so W=A/L. Divide 85 by 10.
An improper fraction is when the numerator is greater. For example, 1 7/8 = 15/8
The answer should be 5/a-a=0
For a parallelogram, the parallel sides must be the same length. This means you can set their lengths equal to each other. Get like terms on the same side to calculate x.
3x-5=2x+3
3x-5+5=2x+3+5
3x=2x+8
3x-2x=2x-2x+8
x=8
x=8
