Y = 20 because both sides equal 25
180-50= 130
130-70=60
60/3= 20
(y=mx+b) Where m is slope and b is y-int.
y=-5/6x-1
For this item, we may let x be the number or liters of apple juice present in the ginger ale. The total volume of the punch then becomes
total volume = 2 + x
Then, considering that 75% of this is apple juice,
x/(2 + x) = 0.75
x = 0.75(2 + x) = 1.5 + 0.75x
x = 1.5 + 0.75x
Also, for this item, the vaue of x is equal to 6 liters.
