which expression shows the first step in dividing 5x + 3 by x?\n$\frac{5x}{3}+\frac{3}{3}$\n$\frac{5x}{x}+\frac{3}{x}$\n$\frac{5x}{5}+\frac{3}{5}$\n$\frac{5x}{5x}+\frac{3}{5x}$

Answer

Explanation:

Step1: Utiliser la propriété de la division

Pour diviser une somme $a + b$ par $c$, on peut écrire $\frac{a + b}{c}=\frac{a}{c}+\frac{b}{c}$. Ici, $a = 5x$, $b = 3$ et $c=x$. Donc $\frac{5x + 3}{x}=\frac{5x}{x}+\frac{3}{x}$.

Answer:

$\frac{5x}{x}+\frac{3}{x}$ (la deuxième option)
