THERE ARE 25 CUB SCOUTS IN pACK 584 THE NUMBER OF SCOUTS IS 5 MORE THAN 5 TIMES THE NUMBER OF ADULT LEADERS FIND THE NUMBER OF A
Aneli [31]

The number of the adult leaders will be 4

<h3>What will be the number of adult leaders?</h3>

A Number of cub scouts in troop 584 is = 25 .As per the statement given in the question "The number of scouts is 5 more than five times the number of adult leaders"

Number of scouts = 5(Number of adults) + 5

Here number of scouts = 25

Therefore, the equation will become as

25 = 5(Number of adults) + 5

5(Number of adults) = 25 - 5

5(Number of adults) = 20

(Number of adults) = 20/5=4

Hence the number of the adult leaders will be 4
