N = x-7
2x = 5n-7
2x = 5(x-7)-7
2x=5x-35-7
-3x=-42
x=14
n=7
7 is the answer
Yes it is proportional!
we know this because with every week that passes, he plays another 2.5 hours if video games. hope this helps:)
<span>Let's called the train that traveled south train A, and the train that traveled east train B
After 3 hours, train A is 180 miles South
and Train B is 150 miles East
Using Pythagoras, distance between is sqrt(180^2 + 150^2)
30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles</span>
