The area of a parallelogram is given by

Now, if we consider the 9.9 inches side as the base, then the height is the one labeled with 5.5 inches.
If instead we choose the 11 inches side as the base, the height is h.
So, we can express the area in this two equivalent ways:

Solving for h, we have

Hello from MrBillDoesMath!
Answer:
b = 0.6
Discussion:
The question can be written as
b - 7.4 = -6.8 => (now add 7.4 to each side)
b - 7.4 + 7.4 = -6.8 + 7.4 => ( note: -7.4 + 7.4 = 0)
b = 0.6
Thank you,
MrB
Yes this is the right answer
4/7 - x = 6/35
You're trying to get x by itself, so you have to subtract 4/7 from both sides.
-x = 6/35 - 4/7
You need both of the fractions to the right of the equal sign to have the same denominator so that we could simplify them, so multiply 5/5 to -4/7.
-4 /7 × 5/5 = -20/35
So, our new equation is :
-x = 6/35 - 20/35
Simplify.
-x = -14/35
Divide both sides by -1.
x = 14/35
Divide by 7.
x = 2/5
