Hi Cassandra. In some cases with math, the answer can be tested by plugging it back in to the original equation.

For example, if you have 2x+5=10, when you solve for it x=2.5. And if you want to make sure that this is the correct answer, plug 2.5 in for x in the equation given. So 2(2.5) + 5=10. You test it and you see that you get 10=10, which is true. So you know that your answer is correct.

I hope this helped.

Casandra,

As withe answer to any question, you should ask "does the answer make sense?". For example, if you are traveling at 60 miles per hour for 60 minutes, you didn't travel 3600 miles (that doesn't make sense). You did travel 60 miles, because you changed the 60 minutes to 1 hour (travel is in miles per hour). With many other math problems you can substitute what you think is the answer, back into the original equation, do the computation to see if what you thought is correct. Hope this helps.

Thanks,

Chris
