First, you would divide 9/72 by 72/72 and would get .125. So every book weighs .125 kg.
Then, to find how much 80 book weigh, you multiply 80 times .125 and get 10.
Lastly, to find how many books weigh 6 kg you, keep multiplying .125 by a number until you reach 6 kg. In this case the number is 48. So 48 books weigh 6 kg.
Hope this helped! ;D
Answer:
John needs 
yards of blue ribbon.
Step-by-step explanation:
We have been given that Jon uses a piece of red ribbon witch is 3/4th yard long. Jon also needs blue ribbon that is 5 times as long as the ribbon. We are asked to find the amount of blue ribbon that John needs.
To find the amount of blue ribbon that John needs, we will multiply amount of red ribbon by 5 as shown below:
Therefore, John needs yards of blue ribbon.
The equation of a line is Y=mx+b
You know that the slope is -2 and the slope is 'm' so sub it into the equation.
Y=-2x+b
To have an equation of a line you need the 'b' or 'y' intercept and the slope.
This means you have to find the 'b' because you already know the slope which is -2. To find the 'b' you have to sub in the coordinates and then solve for 'b'
Y=-2x+b
(x,y)
(3,0)
0=-2(3)+b
0=-6+b
6=b
Therefore the equation of the line is Y=-2x+6 <span />
