The number of marbles in a bag is represented by m. which expression shows the number of marbles in the bag after jack puts 8 more marbles into the bag?

x=m+8

where x is the new no. of marbles

Step-by-step explanation:

Given : The number of marbles in a bag is represented by m.

          Jack puts 8 more marbles into the bag

To Find: Which expression shows the number of marbles in the bag after Jack puts 8 more marbles into the bag?

Solution : Let no. of new marbles after adding 8 more marbles be x

Since there is m marbles in the bag .

So, after adding 8 marbles there will be marbles in bag = m+8

So, the new no. of marbles :

x=m+8

Hence x=m+8 is the required expression .

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
