Answer:
x = 38
x = 18
Step-by-step explanation:
Let one number = x
Let the second number = y
x - y = 20
x must be the larger of the two numbers
x = 2y + 2 Put this equation into the equation above
2y + 2 - y = 20 Combine
y + 2 = 20 Subtract 2 from both sides
y = 20 - 2
y = 18
x - 18 = 20 Add 18 to both sides
x = 38
The answer would be the third number line
X is the size of the bottle. So x/5 + (x/5)/4 + ((x/5)/4)/3 = 2/3 cups
x/5 + x/20 + x/60=2/3; (12x+3x+x)/60=2/3; 16x/60=2/3; (16x)3=(2)(60)
48x=120
x=

= 2

= 2

The bottle is 2

cups
Rewritten: y=15x + 50
slope: 15
y intercept: (0,50)
