Chad wants to buy some books over the internet. each book costs $10.01 and has a shipping cost of $9.96 per order. if chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy? 9.96p − 10.01p ≤ 50, so p ≤ 1 9.96p 10.01p ≤ 50, so p ≤ 2 9.96 − 10.01p ≤ 50, so p ≤ 3 9.96 10.01p ≤ 50, so p ≤ 4

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
