Choice A is false because they are rounding to the nearest tenth (one decimal place) and not nearest hundredth (two decimal places)
Choice B is false as well because 3.825 should round to 3.83. The 5 at the end tells you to round up. 
Choice C is false too. The value 3.824 should round to 3.82. Not sure how they got 3.81, so it seems like a deliberate trick question or silly answer.
Choice D is true. The three decimal values are rounded properly to the correct number of decimal places. 
Therefore choice D is the answer
        
                    
             
        
        
        
Answer:
9
Step-by-step explanation:
3 3/4= 3.75. 
3.75-2=1.75
1.75+5.5=7.25 or 7 1/4
7.25+1.75=9
 
        
                    
             
        
        
        
Replace each occurrence of x by 7. So we have:-
7^2 + 3 / 7 - 9
= 52 / -2
= -26 answer
