Answer:
Kaya found 25 shells on the beach yesterday.Today she found 25 more shell. She sorted all the shells into 5 pile.Which equation can be used to find how many shells are in each pile?
A.s=(25+25)÷5
B.s=25÷5
C.s=(25+25)-5
Equation A can be used to find the number of shells in each piles.
Step-by-step explanation:
Given:
Number of shells Kaya found day before = [tex]25[/tex]
Number of shells she found today = [tex]25[/tex]
According to the question:
She sorted it into [tex]5[/tex] piles meaning we have to equally put them in each pile, for this we have to divide the total number of shells.
Let the number of shells in each pile = [tex]s[/tex]
And total number of shells = [tex](25+25)=50[/tex]
So,
The number of shells in each pile.
⇒ [tex]s=\frac{Total\ no.\ of\ shells}{Number\ of \ piles}[/tex]
⇒ [tex]s=\frac{50}{5}[/tex]
⇒ [tex]s=10[/tex]
From equation [tex]A[/tex] where, [tex]s=\frac{(25+25)}{5} =\frac{50}{5} =10[/tex] gives the same answer.
Then option A is the right choice.
