Answer:
e
Step-by-step explanation:
If you divide 36 by 12, you get 3.
For this to work, whatever the white wax is, it needs to be 3 times as more as 5.
5x3=15
 
        
                    
             
        
        
        
120 + 90 = 210 points
350 - 210 = 140 OR 
   351 - 210 = 141  (if it must be more than 350, you need <em>at least </em>351 points total, or 141 more points, to get a grade B)
        
             
        
        
        
okay. the point has an x and y value. place them into the equation. 
1=m(1)+b
m=slope, and theequation tells you that slope is 7.
1=7(1)+b
now you need to figure out what b is. 
1=7(1)+b
 ^
 1= 7 +b
-7 -7
---------------
-6=B
b is 6. now place it into the equation, replacing the x and y values back.
y=7x-6.
write 7 and 6 in the boxes (the negative for the six has already been provided)
 
        
             
        
        
        
49.5 mph
just multiply the miles by 2 because it is only half an hour
