Two angles lie along a straight line. If m∠A is five times the sum of m∠B plus 7.2°, what is m∠B?

A horizontal line has a ray that extends up and right. The angle formed on the left of the ray is labelled A and the angle formed on the right of the ray is labelled B.

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.
