Answer: 
Answer:
100
Step-by-step explanation:
5•10^-2= 5•1/100 an d that's equal to 1/20 if you divide it with (2•10^3)wich is equal too 2000
you will get 100 as a result
75
Reduction of 12
3 x 4 = 12
Increase of 10
5 x 2 = 10
75 - 12 = 63
63 + 10 = 73
Change = 2 inches (75 - 73)
It has to be the last one, D. I did it over 3 times to make sure.
