Answer:
6x +10
Step-by-step explanation:
Perimeter = 2*(length + width)
= 2* (x+6 + 2x-1)
=2*(3x +5)
=2*3x + 2*5
=6x + 10
The area below the blue line would be shaded because y is less than the equation.
Let x = number of cups drank per week
let y = number of gallons drank per week
x = 1 cup x 7 days
x = 7 cups per one week
y = 7 cups per week x 0.0625 gallons
y = 0.4375 liquid gallons each week
Therefore Pheneg-Xu drinks 0.4375 liquid gallons each week
10 because the ratio is 4/10 and the bottom number is the denominator
