When any lines are parallel that means they have the same slope so the slope of the red line would also have a slope of -3/7
3 is the common difference
So for this question,
we take 50 as 90% first
so to find 100%, 50/90 * 100 =55.6 or = 55 5/9 or = 500/9
3w-5=length
The length plus five would equal three times the width
