tres galgos compiten en una carrera, el primero tarda 40 segundos en dar una vuelta a la pista, el segundo tarda 50segundos y el tercero 60 segundos. cuantas vueltas debe dar cada uno para que vuelvan a coincidir en el punto de salida

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.

step-by-step explanation:

the weight of the object inside the box!

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
