4(1.5c+6)-2c=-9 so we distribute the 4 to 1.5 tand 6 and it will now be broken into this ==>   6c+24-2c=-9 ok now we most combine like terms so the we do 6c-2c= 4c so the problem is now 24-4c=-9 ok now i think we need to solve for c so we subtract 24 to -9  because it is negative it is now -33 so the problem is -4c=-33 divide by -4 and you will get your answer. I hope this helped and is correct.
        
                    
             
        
        
        
Answer:
 
 
Step-by-step explanation:
 
 
 
 
Equation of line in point slope form is given as:
 
 
Plugging the values of m and  , we find:
, we find:
 
 
 
 
 
 
 
 
This is the required equation of line. 
 
        
             
        
        
        
You simply put 40 over a hundred and 55 over n (which is the number were trying to find)  so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
