Answer:
50 inches.
Step-by-step explanation:
Let the length of the each ribbon was x.
Now, she cuts 9 pieces of same length L which means total length is 9L.
Now, doing the same she was left with 5 inches of ribbon. Hence, we have
[tex[9L+5=x.....(1)[/tex]
Similarly, we can write a equation for the second situation.
![2L+40=x......(2)](https://tex.z-dn.net/?f=2L%2B40%3Dx......%282%29)
From equation 1 and 2,
![9L+5=2L+40\\\\7L=35\\\\L=5](https://tex.z-dn.net/?f=9L%2B5%3D2L%2B40%5C%5C%5C%5C7L%3D35%5C%5C%5C%5CL%3D5)
Plugging this value in equation 1,
![9(5)+5=x\\\\x=45+5\\x=50](https://tex.z-dn.net/?f=9%285%29%2B5%3Dx%5C%5C%5C%5Cx%3D45%2B5%5C%5Cx%3D50)
Therefore, the length of each ribbon when she bought them was 50 inches.
