Answer:
A - x = (k-c)/5
Step-by-step explanation:
To solve this problem, we would solve for x like we would in 2x = 6 :
5x + c = k
5x = k-c (subtract c from both sides)
x = k/5 - c/5 (divide 5 on both sides)
x = (k-c)/5 (simplify)

The slope of the line is “rise over run.” That’s the vertical change between the two points (the difference in the y-coordinates) divided by the horizontal change over the same segment (the difference in the x-coordinates).
He saves $200 (the amount of change over the original amount $500
200/500 = 2/5 and 2/5 = 40% (divide 2 by 5 and get .4 which = 40%)
40% discount is the answer to your question
X * 3 = 270
Solving for x, x = 90
So one side is 90m and the other is 3m.
Now find entire perimeter 90+90+3+3=180+6=186m
