Answer:
The answer is 0
Step-by-step explanation:
2 * 2 * 2 = 8
8 * 0.5 = 4
4 - 4 = 0
0 / 2 = 0
Make sure the 0.5 is actually 0.5, because it is hard to tell in that expression. if anything, anything, the steps are the same and all you would need to do is the change the numbers. 
Hope this helps :)
 
        
             
        
        
        
Answer:
(1/3 - 5/6) / 5/6
You want to make 1/3 and 5/6 have the same denominator so you multiply both the numerator and denominator of 1/3 by 2 to get 2/6. You plug that back into your equation to get: (2/6 - 5/6) / 5/6. 2/6 - 5/6 is -3/6. -3/6 divided by 5/6 is -3/6 multiplied by 6/5 which is -3/5. 
 
        
                    
             
        
        
        
As we already have the model that describes the change of the population in Italy in terms of the years that have elapsed, we only have to replace the conditions that are requested in that equation.
 Therefore to find the population of Italy in the year 2000 (t = 10 years)  substitute t = 10 in the equation and have:
 
  million people
 million people
 To find the population of Italy in 2008 (t = 18 years)
 substitute t = 18 in the equation and have:
 
  million people
 million people
 To predict the population in Italy for 2015 and 2020 with this model, we substitute in the equation t = 25 and t = 30
 t = 25
  
  million people
 million people
  t = 30
  
  million people
 million people
