65 people=20 minutes
20*3=60 minutes which is 1 hour
65*3=195 people per hour (This is the rate per hour)
195*6=1,170 people per six hours

Option B is correct.
Step-by-step explanation:
Paul was asked to use the elmination to find the solution to the system of linear equations

What are the missing steps in his work below?

So, the step missing is multiplying equation 1 by 2 i.e
![2\times [5x + 4y = 1] \\10x + 8y = 2](https://tex.z-dn.net/?f=2%5Ctimes%20%5B5x%20%2B%204y%20%3D%201%5D%20%5C%5C10x%20%2B%208y%20%3D%202)
So, Option B is correct.

Answer:
AD= 15
AB=30
Step-by-step explanation:
We are given that the Point D bisect the line segment AB
Hence AD = DB
AD= 4x-1
BD=9x-21
Hence
4x-1=9x-21
adding 21 on both sides and subtracting 4x from both sides
4x-4x-1+21=9x-4x-21+21
-1+21=5x
5x=20
dividing both sides by x we get
x=4
Hence
AD = 4x-1
= 4(4)-1= 16-1=15
AD= 15
AB = 2 x AD
= 2 x 15
= 30
