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 .

Triangle ABC:
AB=2
BC=x+5
CA=x+7
Triangle XYZ:
XY=4
YZ=?
ZX=4x-2
x=?
XY/AB=ZX/CA
4/2=(4x-2)/(x+7)
Simpliying:
2=(4x-2)/(x+7)
Solving for x: Cross multiplication:
2(x+7)=(4x-2)
2x+14=4x-2
2x+14-2x+2=4x-2-2x+2
16=2x
16/2=2x/2
8=x
x=8
Answer: The value of x is 8
Answer: 1600batteries
Step-by-step explanation:
Let the number of inspected battery be y
2.5% of y = 40
5/2% of y = 40
Change 5/2% to fraction
5/200 × y = 40
5y/200=40
Cross multiply
5y= 40×200
5y=8000
y=8000÷5
y=1600
The total number of battery inspected is 1600.
