Answer:
I think it would be true.
When trying to find value of variable, always try to get it alone.
5a-2b=c
Add 2b for both sides.
5a=2b+c
Divide by 5
Answer: 2b+c/5
The answer is {1, 2, 10, 50, 75}. It has a median of 10 and a mean larger than 10
So u will do 88+84=172+88=260+91=351 and that is all four tests added up now u have to divide the answer by 4 because it was four tests averages
351/4=87.75 wich is aproxamately 88
so with all four of them added wich is 351 u will add the answer choices so 351+96=447/5=89.4 wich is aproxamately 89
351+97=448/5=89.6 wich is aproxamately 90
351+98=449/5=89.8 wich is aproxamately 90
351+99=450/5=90
so i would say that 99 points is the one she needs to score because it isnt asking for aproxamately
so it is 99 points
