Jamie wants to work no more than 30 hours per week at his two part-time jobs. the first job pays him $14 per hour and the second job pays him $16 per hour. he must earn more than $250 per week to pay all of his bills. which inequality models this situation?

a. x + y > 250; 14x + 16y ≤ 30
b. x + y < 30; 14x + 16y ≥ 250
c. x + y ≤ 30; 14x + 16y > 250
d. x + y ≥ 30; 14x + 16y < 250

D

Step-by-step explanation:

Because the problem says he needs to earn MORE than 250 dollars a week, you need to have the greater than sign without the equal to underneath it. D is the only possible answer for this question for that reason.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

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.
