The remainder (which is what Blake says is the remainder), can never be more than the number you are dividing by (the dividend), which in this problem is three.
Divide 136 by 3 and you will prove that answer is incorrect.
So a parallel line is were the lines never meet but the perpendicular line meet at a right angle
Form an equation then solve:
8x+15=7
8x=-8
x=-1
444 = x + (x-54)
x = 249
If there ate 54 fewer cheeseburgers than there should be 195 cheeseburgers and 249 hamburgers.
