Step-by-step explanation:

I am going with A12x + 7yx = # of adult and y = # of childrenadults cost 12 and children cost 7 <

B doesn't make much senseu could say x was for girls and y for boys...but u already know how many there areso I am not sure what the x and y could stand for.

C does't make much sense eitherx would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there areso not sure what x and y could stand for

D. wrongbecause the box containing x 7 oz packages and y 12 oz packages12x + 7yfor this one to be correct, it would have to have x 12 oz packages and y 7 oz packages

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

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.
