Decide whether the rates are equivalent. 1. 24 laps in 6 minutes 72 laps in 18 minutes 2. 15 breaths every 36 seconds 90 breaths every 3 minutes show work.

#1 is correct

Step-by-step explanation:

24 laps divided by 6 minutes equals 4 laps per minute.

72 laps divided by 18 minutes equals 4 laps per minute.

15 breaths divided by 36 seconds does not equal the same rate as 90 breaths divided by 3 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.
