A number is divided by four. The result is added to five. This result is multiplied by three to give 27. What is the number?

x=16

Step-by-step explanation:

We'll say that x represents the number.

3(+5)=27      given equation

+15=27        distributive property

3x/4=12         subtract

3x=48             multiply

x=16               divide

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.
