55 if you mean one half
5500 if you mean 50 times 110
60 if you mean 50 from 110
        
             
        
        
        
Add like terms 
-4x+x=-3x
6-2=4
So the simplified term is 4-3x
        
             
        
        
        
Answer:
D
Step-by-step explanation:
 
        
                    
             
        
        
        
the answer is 20
1/10 of 200 is 200* 1/10 = 200/10 which is 20
 
        
             
        
        
        
The area is the product of length and width, which is to say that the length and width are factors of the area.
Assuming the dimensions are integers, you want factors of 84 that differ by 5.
... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12
The last of these pairs differ by 5, so ...
- the length is 12 inches
- the width is 7 inches.
