Answer:
5
Explanation:
Let the number equal x. Half the number is then 
x
2
 and the reciprocal of that is 
2
x
The reciprocal of the number is 
1
x
 and half that is 
1

x
then

Answer:
Should be C
Step-by-step explanation:
Only the same power number can be use to add or subtract :)
But why is A, B and C same kinda stuff?
 
        
             
        
        
        
The angles will help you tell the difference. In a rectangle, all angles are 90 degrees. In a rhombus, the 2 opposite facing angles are the same and all side lengths are the same. 
Hope I helped. :P
        
                    
             
        
        
        
Slope = (-12 - 43)/(4 +7) = -55/11 = -5
y = mx + b
43 = -5(-7) + b
43=35+b
b = 8
equation
y = -5x + 8
