Answer 1

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.

Step-by-step 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

`C=5L+3`

Given that

`C=13`

Then putting this value we get

`\begin{gathered} 13=5L+3 \\ \Rightarrow-5L=3-13 \end{gathered}`
`\begin{gathered} \Rightarrow-5L=-10 \\ \Rightarrow L=(-10)/(-5) \end{gathered}`
`\Rightarrow L=2`

Final answer:

The number of adult leaders is

`2`
