0, sqrt(9), 16.00, -4, -2, and -5 are all whole numbers because they all simplify to numbers without decimals
It is E because I did the test and it was easy so txt me if you need help
From what we know, p is 20 more than q. So, we can assume p = 20 + q. Q can also be found by subtracting 20 from both sides. So, q = p - 20.
Hope this helped!
