Answer:
B: 8
Step-by-step explanation:
we are given two numbers which we can use to help solve this problem
A: the number of hours the dishwasher is being used
B: how long it takes the dishwasher to do each load
using this info we can find how many loads were washed in 10 hours by dividing the time it takes for each load by how many hours were spent.
10 / 1.25 = 8
(2b+3) (b+7)
2b²+17b+21
2b²+14b+3b+21
2b(b+7) + 3(b+7)
x=-14
-2(x-8)+4x= -12
-2x+16+4x=-12
2x=-28
C. 6%
0.04+0.02
=0.06×100%
= 6%
hope it helps...
have a great day!!

First you have to find the medians which is when you put the numbers in number order and find the one in the middle.
Class A: 60,65,70,70,75,80,80,85,90,90
=77.5
Class B: 75,85,85,85,90,90,90,90,95,100
=90
That the class B is more advanced, and they probably studied.
