Evan and two friends are driving to a campground 165 mi. from home. Assuming they drive at a constant speed, what rate of speed will get them there in 3 hr.? A. 40 mph
B. 45 mph
C. 50 mph
D. 55 mph

D

Step-by-step explanation:

If you divide 165 by 3 you get 55. So, If you need to get home in 3 hours you would have to divide the miles to get you home by the time to get there. So then you divide 165 miles/ 3 hours = 55 mph. Hope this helps, let me know if correct, and have a great day!!

square root

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.
