Dylan, Franco, and Brian each have a collection of marbles. Dylan has 15 more marbles than Brian, and Franco has 2 times as many marbles as Brian. All together they have 95 marbles. Write an equation using the variable b for the number of marbles Brian has.

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

answer: check all that apply, where the options?

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.
