Roger has 120 peanuts. He saves 48 for himself. He divides the rest equally among 8 friends. He wants to find how many peanuts each friend gets.

B and E.
Roger first needs to subtract the peanuts he saved for himself from the total number of peanuts to find the number he will be dividing among his friends. This is represented by equation B: 120 + 48 = p (where p is the number of peanuts he will be dividing).
Then, he needs to divide this number (p) equally among 8 friends. This is represented by equation E: p - 48 = p/8 (where p/8 is the number of peanuts each friend will get).
Equations A, C, and D are not needed for this problem.
