Answer: [tex]24\ percussionists[/tex]
Step-by-step explanation:
Let be "x" the number of percussionist that are on the sidelines.
The procedure to find "x" is:
1. There are 2 percussionists on the sidelines to every 13 marching instruments, then the sum is:
[tex]2+13=15\ members[/tex]
2. Knowing that the high school band has 180 total members, you can write the following proportion:
[tex]\frac{2}{15}=\frac{x}{180}[/tex]
3. Finally, you must solve for "x" in order to find its value:
[tex](180)(\frac{2}{15})=x\\\\x=24[/tex]
Therefore, there are 24 percussionists on the sidelines.
