Theresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests. what is the lowest score she can get on the fifth test and still finish with an average score of 90 points? a. 94 points b.95 points c.96 points d.97 points plz m

90 x 5 = 450 ( total points for  tests)

88 + 84 + 88 + 91 = 351 ( total of 4 tests)

450 - 351 = 99

 if she scores a 97 she would have 88+84+88+91+97 = 448. 448/5 = 89.6 which would round to a 90

 she needs at least a 97

 Answer is D

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
