Answer:
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 .
