Here's the equation for direct variation. k=y/x    [ f(x)=y]
Find k
k= 48/8=6
6=y/2
y=12
Hope this helps.

Answer:60 balloons 
Step-by-step explanation: 0.80 times 75 is 60 and 125- 65 is 60 
 
        
                    
             
        
        
        
x = the length of one piece
y = the length of the other piece
the total length is 100 cm this means 
x + y = 100
one piece is 16 inches longer than the other
first we need to convert inches to cm: 
1 in = 2.54 cm
16 in = 2.54*16 = 40.64
now we can write
x = y + 40.64
by solving the system of equations
x + y = 100
x = y + 40.64
we find
x = 70.32 cm
y = 29.68 cm
the lengths of the two pieces are 70.32 cm and 29.68 cm.
 
        
             
        
        
        
500,000 + 8,000 = 508,000
