Antonio Conley · Answer 1

part a:

8n-10 + n+4 = 2n+3 + 3 (2n-1)

part b:

n = 6

baseball = 38

flag football = 15

kickball = 10

soccer = 33

Step-by-step explanation:

part a:

8n-10 + n+4 = 2n+3 + 3 (2n-1)

part b:

9n - 6 = 2n+3 + 6n-3

9n - 6 = 8n

n = 6

now plug in to every equation to solve for how many student play in that sport

baseball : 8 (6) - 10 = 38

flag football : 2 (6) + 3 = 15

kickball : (6) + 4 = 10

soccer : 3[2 (6) - 1]=33
