<em>Greetings from Brasil....</em>
As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD
5X - 1 = 7X - 13
X = 6
EF = EG + GF
6X - 4 = EG + 13 x = 6, so
6·6 - 4 = EG + 13
<h2>EG = 19</h2>

These two have different denominators, so you find the least common multiple. This problem goes to be 2/8+5/8, which equals 7/8。
We know that the price of all the fabrics is the same. However, the length of the fabrics is different. We have to determine which fabric is the longest.
Option A:
= 8.6
Option B:
= 8.25
Option C:
= 8.6667
Option D:
= 7.33....
Hence, the longest fabric is the one given in option C, and its length is 8.6667
I don't get how it would be a system of equations.
