if Joyce saved $70
at 75% off, Joyce saved 25%
so, $70 is 25%
To find the total price which is 100%, multiply $70 by 4 ( because 25% x 4 = 100% )
so the original price is $70 x 4 = $280
There are two ways to do this. One is by adding up the squares, which takes a while. The other way is if you notice that the length along the bottom is the same as that long the top, and the same is true for the sides. While it does not appear this way at first, imagine that that was the floor plan of a house. If you looked at it from the side, you wouldn't see the dent in the corner, only one side. Since the length of the top is 13 units, from -7 to 6, and the side is also 13 units, from -6 to 7, the answer is

52 units long.
Answer:
$5692.80
Step-by-step explanation:
Add 20% (aka 20% more than now since it decreased) and then get your answer!
Answer:
1) Angle L = angle J : Given
2) Line KJ || line LM: Given
3) angle KML = KMJ: They are alternate interior angles
4) 180 - angle L - angle KLM = angle LKM
180 - angle J - angle KJM = angle JMK
5) because you know two angles of triangle, you know the third. Because angle L = angle J and angle KLM = angle angle KJM, then the remaining angle LKM must equal the remaining angle JMK
