Salutare!:)

[tex]m.a = \frac{4 + 4 + 5}{3} = \frac{13}{3} = \boxed{4.(3)} \\ \\ m.a = \frac{4 + 4 + 6}{3} = \frac{14}{3} = \boxed{4.(6)} \\ \\ m.a = \frac{4 + 4 + 7}{3} = \frac{15}{3} = \boxed{5} \\ \\ m.a = \frac{4 + 4 + 8}{3} = \frac{16}{3} = \boxed{5.(3)} \\ \\ m.a = \frac{4 + 4 + 9}{3} = \frac{17}{3} = \boxed{5.(6)} \\ \\ m.a = \frac{4 + 4 + 10}{3} = \frac{18}{3} = \boxed{6} [/tex]
