Answer:
12 1/3
        
                    
             
        
        
        
The answer is D
Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6 
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.  
        
             
        
        
        
Answer:
B
Step-by-step explanation:
It's B because two negatives equal a positive. 
C. The absolute value of -45 is 45, leaving the extra negative to hang on in there ---> -|-45|= 45= (bring the negative back over) -45
D. Self explanatory its -45 alone lol.
 
        
             
        
        
        
13152 divided by 8 equals 1644
1644 times 8 and then you would get your answer which is 13152
