So adding a rational number, like 2, it would be irrational still:

That being said, answer C is wrong

Now, what is 2/2? Or 4/1? Whole numbers are one of the 3 types of rational numbers.

Thus the answer appears to be D

Now lets use the process of elimination to double check the

The wording of your question is what will help us out here:

Which of the statements using operations on rational or irrational numbers always results in a rational number?

Because of that, any of the choices that involve a irrational number can result with another irrational number like so:

And there you go, the only answer that hasn't been proven wrong is answer D.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
