Question

10q - 30 is equivalent to _____.

Answer 1

For this case we must find an expression equivalent to:

$10q-30$

We look for the factors of 10 and 30:

10: 1,2,5,10

30: 1,2,3,5,6,10,15,30

The greatest common factor of both numbers is 10.

Then, we can rewrite the expression as:

$10 (q-3)$

Answer:

$10 (q-3)$
