) 30 marbles are to be divided into three bags so that the second bag has three times as many marbles as the first bag and the third bag has twice as many as the first bag. If x is the number of marbles in the first bag, find the number of marbles in each bag.

The number of marbles in the first bag=  5  

The number of marbles in the second bag = 15

The number of marbles in the third bag = 10

Step-by-step explanation:

Given that

Total number of marbles= 30

Lets take, the number of marbles in the first bag= x

The number of marbles in the second bag = 3 x

The number of marbles in the third bag = 2 x

Therefore

The total number of marbles = x + 2 x + 3 x = 6 x

6 x = 30

x= 6 marbles

We  can say that

The number of marbles in the first bag=  5  

The number of marbles in the second bag = 15

The number of marbles in the third bag = 10

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
