As part of their study of the Native American basket weaving, Lia's class is making wicker baskets. Lia starts with a strip of wicker that is 36 inches long. From the strip, she first cuts one piece but does not know it's length, and then she cuts a piece that is 6 1/2 inches long. The piece left is 7 3/4 inches long. What is the length of the first piece she cut from the strip?

If you would like to know the length of the first piece Lia cut from the strip, you can calculate this using the following steps:

36 inches - x - 6 1/2 inches = 7 3/4 inches
36 - x - 13/2 = 31/4
36 - 13/2 - 31/4 = x
x = 144/4 - 26/4 - 31/4
x = 87/4
x = 21 3/4 inches long

The correct result would be 21 3/4 inches long.
