Answer:
51/9 or 5 2/3
Step-by-step explanation:
First, multiply both sides by b-1 using the distributive property.
6/(b-1)=9/7
6=9(b-1)/7
6=(9b-9)/7 Multiply both sides by 7.
42 = 9b-9 Add 9 to both sides.
51 = 9b Divide both sides by 9.
b = 51/9 or 5 2/3
Answer:
h = 20
Step-by-step explanation:
So the first thing we need to do here is distribute our one third so we can then deal with the 18 on the other side of the equation.
So lets distribute!
1/3(3h-6) = h - 2
This is because 1/3 x 3 = 1 and 1/3 x 6 = 2
We could also re-write both of these above to get
3/3 = 1 and 6/3 = 2
So now we have
18 = h - 2
All that is left now is to add two to both sides!
Which leaves h = 20
The answer to your question is c.
Answer:
last two numbers are 10,so their mean is 10
adding all means give us the mean of total data
