Answer:

10

Step-by-step explanation:

w is the variable, you're trying to find what that variable could be. There are 5 boxes so you are trying to find "What minus 2, times 5, is equal to 40." OR (w-2)5=40. 8 times 5 is 40, but to compensate for the -2, add two to the 8 to get 10! hope this helps :)

Answer:

4

Step-by-step explanation:

There are 5 boxes.  Something times 5 is 40.  But,  w-2 has to equal 40.  Since 4 times 5 is 40, w is equal to 4.  4-2=2.  Replace w-2 with 4.  There are still 5 boxes.  So, multiply 4 x 5 and you get 40.
