Question

Cel mai mic numar natural n pentru care 5n+3. supra 24 > 7 supra12 este ? URGENT!!!

Answer 1

5n + 3 / 24 > 7 / 12
5n + 3 > 14
5n > 14 - 3
5n > 11
n > 11/ 5
n > 2,2
deci n numar natural trebuie sa fie cel putin 3

Answer 2

 [tex]Daca\;\frac{5n+3}{24}\ \textgreater \ \frac{7}{12}\;\;atunci\,,\,n_{minim}= ?\;\\ \frac{5n+3}{24}\ \textgreater \ \frac{7}{12}\;\Leftrightarrow\;\;\frac{5n+3}{24}\ \textgreater \ \frac{14}{24}\;\rightarrow\;5n+3\ \textgreater \ 14\\adica: n\ \textgreater \ (14-3):5=2,2\rightarrow\;n_{minim}=3\,\in\,\mathbb{N}[/tex]
