What is the value of x in the figure below?? please help!

B) 24 degrees

Step-by-step explanation:

As this is a right angle with a total of 90 degrees you would first minus 42 from 90, which gives you 48. This now leaves you with just the 2x. As we know that 2x is 48 to work out x you would simply divide 48 by 2, which gives you 24.

1) Minus 42 from 90.

2) Divide 48 by 2.

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.
