The helvie family drinks 1.75 gallons of milk every 4.5 days. what is the unit rate of milk they drink per day

0.39 gallons per day.

Step-by-step explanation:

We have been given that the Helvie family drinks 1.75 gallons of milk every 4.5 days. We are asked to find the unit rate of milk they drink per day.

To find the unit rate of milk they drink per day, we need to divide total quantity of milk by total number of days.

Therefore, the unit rate of milk they drink is approximately 0.39 gallons per day.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
