Answer: 80%
Step-by-step explanation:
To find the average, add all the grades and divide by the number of grades
sum of all grades/number of grades
85 + 100 + 88 + 80 + 95 + x/6
She wants to have an 88, so we can set the expression above equal to 88
448 + x/6= 88
Multiply by 6 on both sides
448 + x = 528
Subtract 448 on both sides
x=80
She needs to score at least an 80 to get an 88 average.
Hope this helped!

Answer:
A = 4 11/16 or 4.6875
Step-by-step explanation:
3 3/4 = 3W
divide both sides by 3
15/4 divided by 3 = W
15/4 x 1/3 = W
5/4 = W
A = L x W
3 3/4 x 1 1/4 = 15/4 x 5/4 = 75/16 = 4 11/16
there is no B i see A and -5A unless its for -5A??
1 and 11/12 hours I think
