Answer: 900 inch
There is 3 ribbon in this question, Red ribbon(R), green ribbon(G) and purple ribbon(P). The relation would be
1. R= 9 inch
2. R= 1/10 G
3. P= 10 G
If you insert equation 1 into 2 then you will get:
9inch= 1/10G
G= 90 inch
After that insert the new equation into equation 3:
P= 10x 90 inch
P= 900inch

Answer:
![1.9*10^{7}\ people](https://tex.z-dn.net/?f=1.9%2A10%5E%7B7%7D%5C%20people)
Step-by-step explanation:
Let
y -----> the population of the entire state of New York
x -----> the population of Geneseo
we know that
The linear equation that represent this problem is equal to
![y=2.5*10^{3}x](https://tex.z-dn.net/?f=y%3D2.5%2A10%5E%7B3%7Dx)
we have
![x=7,600\ people](https://tex.z-dn.net/?f=x%3D7%2C600%5C%20people)
substitute in the equation and solve for y
![y=2.5*10^{3}(7,600)](https://tex.z-dn.net/?f=y%3D2.5%2A10%5E%7B3%7D%287%2C600%29)
![y=19,000,000\ people](https://tex.z-dn.net/?f=y%3D19%2C000%2C000%5C%20people)
Convert to scientific notation
![19,000,000=1.9*10^{7}\ people](https://tex.z-dn.net/?f=19%2C000%2C000%3D1.9%2A10%5E%7B7%7D%5C%20people)
Your answer would be 1.571428... then a bunch of numbers. use a calculator! hope this is helpful
