Step-by-step explanation:
Given part in the question is :
No of pieces of jewelry given by Grandma Gertrude = 13
No of pieces of jewelry given by Grandma Fien = y
There are 5 Carlson sisters.
Total no of pieces = y + 13
No of pieces received by jewelry is y+13 divided by 5. So,
[tex]\dfrac{y+13}{5}[/tex]
Hence, each sister will receive [tex]\dfrac{y+13}{5}[/tex] pieces of jewelry.
