Khloe used 2 1/4 gallons of paint on her living room walls. she used 4 times as much paint for her kitchen and dining room walls. how many gallons of paint did khloe use for the kitchen and dining room walls?

9 gallons

Step-by-step explanation:

Since Khloe used 4 times (4x) as much paint for the kitchen and dining room walls, you can take the amount she used on the living room walls and multiply by 4:

maybe i can

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
