Your cell phone plan costs $39.99 per month plus $.15 for each text message you send or receive. you have at most $45 to spend on your cell phone bill. what is the maximum number of text messages that you can send or receive next month?
-what information do you know? what information do you need?
-what inequality can you use to find the maximum number of text messages that you can send or receive?
-what are the solutions of the inequality? are they reasonable?

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

d
