Araceli uses 8.5 pints of blue paint and white paint to paint her bedroom walls. 4/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

2.125

Step-by-step explanation:

multiply 8.5 x 5/4 which gives you 10.625 and then 10.625 - 8.5 is 2.125

i think c. but don't trust it.

step-by-step explanation:

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.
