When Rachel last checked the clock it was 3:52 pm. It is now 5:00 pm.

How much time has elapsed?

1 hour and 8 minutes or 68 minutes.

Step-by-step explanation:

For this question I would start by finding how many minutes it would take to get to 4pm since it's the closest hour to 3:52 pm.

If we think of the 00 in 4:00 as 60, then we can do 60-52=8.

Then we know that 4:00 + 1 hour is 5:00.

To find the final answer add 8 minutes + 1 hour, which is 1 hour and 8 minutes.

This can also be answered as 68 minutes because, 60 minutes (1 hour) +8 minutes = 68 minutes.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
