Given:
There are 13 cub scouts in troop 645.
The number of scouts is 3 more than five times the number of adult leaders.
Required:
We have to find the number of adult leaders.
Explanation:
Let L denotes the number of adult leaders and C denotes the number of cub scouts.
Then according to the question, we get the following equation
[tex]C=5L+3[/tex]Given that
[tex]C=13[/tex]Then putting this value we get
[tex]\begin{gathered} 13=5L+3 \\ \Rightarrow-5L=3-13 \end{gathered}[/tex][tex]\begin{gathered} \Rightarrow-5L=-10 \\ \Rightarrow L=\frac{-10}{-5} \end{gathered}[/tex][tex]\Rightarrow L=2[/tex]Final answer:
The number of adult leaders is
[tex]2[/tex]
