Answer:
I think B , C AND E  are right.... I hope im right! 
Step-by-step explanation:
b - 7 is a coefficient 
c- 2v + 5+7u is written as a sum of the.....
e - 5 is a constant 
 
        
             
        
        
        
First you would have to convert , so 12 inches = 1 foot . So do 12 X 16= 192inches, then subtract 192-6=186inches should be the difference IN INCHES. If you need it in feet divide 186 by 12 which should give you 15.5feet
        
             
        
        
        
Answer:
Slope- intercept form   y = 200 x + 500
Step-by-step explanation:
Given that the equation
        200x - y + 500 = 0
where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours
The slope-intercept form
                 y = m x +C
Given equation  200x - y + 500 = 0
                           200 x + 500 =y
                        y = 200 x + 500
Slope of the equation m = 200 and y-intercept 'C' = 500
