The amount of decrease is (80 - 64) = 16
The fraction of decrease is the fraction of the original amount that disappeared.
That fraction is (16 / 80) = 1/5 = 0.2
To change a decimal to a percent,
move the decimal point 2 places that way ==> .
0.2 = 20%

Answer:
x= 4/5
y= 2/5
Step-by-step explanation:
3x-y=2
2x+y=5
solve them so that they are in y=mx+b form
3x-y-3x=2-3x
-y= -3x+2
y= 3x -2
2x+y -2x= 2-2x
y= -2x+2
now use the substitution method to get your points
3x -2= -2x+2
3x -2+2= -2x+2+2
3x= -2x+4
3x+2x= -2x+4+2x
5x=4
x= 4/5
now substitute x into any of the 2 equations
y= 3x -2
y= 3(4/5) -2
y= 2 2/5 -2
y= 2/5
