babymother [125]

Answer:

Charlie = 5 + x

Danny = x - 8

Eric = 3x

Step-by-step explanation:

Given

Billy's Marble = x

Required

Determine a,b and c

a. Charlie's Marble

"5 more" means 5 + or + 5

Since Billy's Marble is represented with x, then Charlie's Marbles will be

Since Billy's Marble is represented with x, then Danny's Marbles will be

Danny = x - 8

c. Eric Marbles

Having "three times as " means we have to multiply Bill's marble by 3;

Since Billy's Marble is represented with x, then Danny's Marbles will be

Eric = 3x
