There is 16 ounces in 1 pound. so you would want to divide 12.40 by 5 = $2.48 . so its $2.48 for a pound divide by 2 and you answer would be $1.24... i hope that helps

Ok, you can refer to the midpoint formula to find the endpoint.  Here goes...
MP=(2,-7) and EP=(8,-5)
Let x represent the missing endpoint.
(8+x)/2=2      NOTE: =2 represents first number of MP and the representation of number 8 is self explanatory.  You have two endpoints but need to identify the other endpoint so you divide by 2.  Then, multiply by two on both sides.
2(8+x)/2 = 2*2
16+x/2=4 do the next step (simplify) on the left side of equation 16x/2=8
Now, subtract 4-8=-4  So, the x coordinated of the missing endpoint is -4.
        
                    
             
        
        
        
Answer:
16
Step-by-step explanation:
you would get c alone so you subtract 5 to the other side
 
        
                    
             
        
        
        
Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation  then plug in the numbers
 then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then 
you get y=0*x+1 
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)
