Answer: 585 maybe??
Step-by-step explanation:
450/100 = 4.5
4,5 = 1 percent of the total amount.
4.5 x 25 = 112.5
112 = 25 percent of 450
4.5 x 5 = 22.5
22.5 = 5 percent of 450
Hope u understand and that this helps:)
part A
if the paperbacks are 40% less, that means 100% - 40% = 60%, they actually are 60% of the price of the hardcover ones.
part B
so, if they return it, they get 1/3 credit, if they try to sell it, is half off, which is more than 1/3. 22 got damaged.

I don't think she is incorrect, $17.5 is close to $20, she didn't say it was exactly $20, just thereabouts, and 17.5 is around that much.
Your answer would be y + 9 = m(x + 6)
Answer:
It should be congruent by the AAS congruence theorem
Step-by-step explanation:
The error is in the congruence theorem.
We know that the 2 angles are congruent and one of the sides are congruent. This means that it can either be congruent by ASA or AAS.
It is actually congruent by AAS because it include two angles and the side is opposite of one of the angles.
