Answer:
The remainder is zero
Step-by-step explanation:
To find the remainder we will use the long division
⇒(1)
⇒(2)
⇒(3)
From (1) , (2) and (3)
The quotient of the long division is 
 and no remainder
So the remainder is zero
* If you want to check your answer Multiply the quotient by the divisor

 
        
             
        
        
        
1. 1,728
2. You can't tell because it doesn't say the amount one serving will serve, and how many servings she is serving, and how many people come to her party. Sorry!!
I hope I helped with the first one!
        
             
        
        
        
2x+3y=6
3y=6-2x
y=2-2/3x
y=-2/3x+2 
the 3rd one is correct
        
             
        
        
        
OK first convert one of the equations into Y=MX+b form 
Y-2x = 3
Add 2X
Y = 2x +3 
Now substitute this equation in the other one.
So it would be
3X - 2Y = 5
3X-2(2x+3) = 5 
Now solve for y
3X - 4X - 6 = 5 
-1X - 6 = 5 
Add 6
-1X = 11
X = -11
Now substitute this into one of the equations
Y - 2X = 3
Y -2(-11) = 3
Y +22 = 3 
y = 3-22
y = -19
