To get a b in math, alexandria pappas must average 80 on five tests. scores on the first four tests were 8484, 7575, 8181, and 7676. what is the lowest score that she can get on the last test and still get a b?

84

Explanation:

Total for 5 tests = 80 x 5 = 400 

Total for 4 tests = 84 + 75 + 81 + 76 = 316

5th score = 400 - 316 = 84

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
