Question

Jarrett splits his bag of j jelly beans into two equal piles and gives one pile to his brother. He then gives his brother seven more beans. Write an algebraic expression to represent the number of beans his brother has?

Answer 1

½j + 7

Explanation:

j = jelly beans

Jarrett splits his bag of j jelly beans into two equal piles

so now we have two equal piles of the jelly beans

½j and ½j

and gives one pile to his brother

so right now the brother has
½j

He then gives his brother seven more beans

we add 7 to our equation and now

this is the algebraic expression that represents the number of beans the brother has:

½j + 7

Answer 2

Answer: j/2+7= the amount his brother has

Explanation:

I'm going to do an example equation, so let's pretend j=30

Step 1: Divide the jelly beans in half (by 2)

30/2=15

Step 2: So now they each have 15 jellybeans, but if Jarrett gives his brother 7 jellybeans...

15+7= 22
