This is an example of the commutative property of multiplication.
That property states:
So using that property, we can figure out that
3 should be in the blank.

-14
Step-by-step explanation:
Your system could be anything, just remember that input should be half than the output.

If for the slower printer it takes 10 hours for the whole thing, how much has it done in 1 hour? well, since it takes 10 hours total, in 1 hour it has only done 1/10 th of the whole work.
the faster printer however, can do it in 6 total, how much has it done in 1 hour? well, 1/6 of the whole work.
now, let's say, they both work together, and it takes "t" hours to finish the whole thing with both rolling.
let's add both rates to see how much that is,
which is 3 hours and 45 minutes.
