<h3>The answer is:</h3><h2>D. 5 hours</h2><h2 />
The equation should be:
(70x) - (20x) = 250
Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.
Use an educated guess. I'm going to go with 5 because it seems reasonable.
(70 * 5) - (20 * 5) = 250
Let's check to see if it equals 250:
Therefore, the answer is D. 5 hours.

Steps to solve:
5(x + 1) = 20
~Distributive property
5x + 5 = 20
~Subtract 5 to both sides
5x + 5 - 5 = 20 - 5
~Simplify
5x = 15
~Divide 5 to both sides
5x/5 = 15/5
~Simplify
x = 3

I need a question to answer first.
The answer would be d , because you have to add how many of each fish to equal up to the sum of 420 . which is x y . so the first equation is x + y = 420 . then it says he bought 6 times as many parrotfish as he did angelfish so you would have to multiply x which represents angelfish by 6 . to get the second equation of y = 6x .
