Step-by-step explanation:
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
Formula to find the slope:
m = y2-y1 / x2-x1
(4,3); (8,5)
m= 5-3 / 8-4
m = 2/4
m = 1/2
Therefore, the slope of the line that passes through these points is 1/2
2 + 3 = 5
3 + 7 = 10
4 + 5 = 9
5 + 8 = 13
6 + 7 = 13
7 + 8 = 15
