Billy has x marbles. Write an

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

$Charlie = 5 + x$

b. Danny's Marbles

Having "8 fewer" means we have to subtract 8 from Billy's marble;

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

$Eric = 3 * x$

$Eric = 3x$
