a carpenter has three sheets of plywood that are each 6.85 feet long. a 3.4-foot piece is cut from one sheet 0.5-foot piece is cut from another piece. How many feet in plywood is left in all

16.65 feet

Step-by-step explanation:

Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:

6.85

−

3.4

=

3.45

feet left

If we cut off 0.5 feet off another board, that board has:

6.85

−

0.5

=

6.35

feet left

So, if we take our three new boards, the total length of plywood left is:

6.85

+

3.45

+

6.35

=

16.65

feet

Hope this helps!

the solution is h=10 because you add 9 to each side of the equation.
