Yes.
-- Take 10/50.
-- Divide numerator and denominator by 2.5 ,
   (Or multiply them by  0.4 .)
-- You now have  4/20 .

Answer: Apply the Sum/Difference Rule
             d/dx(7x)-d/dx(8)
                d/dx(7x)=7
                d/dx(8)=0
                   7-0=7
                     
Step-by-step explanation: The answer is 7
 
        
             
        
        
        
Answer:
213.3
Step-by-step explanation:
The volume of a pyramid is 1/3 base times height. 
Using this formula, our square base is 8*8, or 64 square units. 
Multiplying that by the height, 10. We get 64*10, 640. 
Finally dividing by 3, we have 213.3333333333... 
Rounding that to the nearest tenth, 213.3.
