Answer: 121
Step-by-step explanation: Here is one way to show the total number of players and coaches in the soccer league using an open number line:
0------------------37-------------------158
We can see that there are 37 coaches, so we mark that point on the number line. Then we can see that the total number of players and coaches is 158, so we mark that point on the number line as well. Finally, we can see that the distance between the two points represents the number of players in the league:
158 - 37 = 121
So there are 121 players in the soccer league.
