Answer: E. 40 
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to zero, so input zero in for y and solve for x to find the x-intercept. 
1/2x + 3/5(0) = 20 
1/2x = 20     
  x = 40 
 
        
             
        
        
        
If you are starting off with zero then your end product would be zero
