A Rock climbling gym charges Non-members $16 per day to use the gym and $8 per day for equitment. Members pay a yearly fee of $450 for unlimited climbing, and $6 per day for equitment. Write and solve an equation (or a system of equations) to find how many times you must use the gym to justify becoming a member.

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

positive
