Question

Dê o valor de X em:

a) $\frac{x^{2}}{6} = \frac{6}{1}$

b) $\frac{2x+1}{x} = \frac{3}{4}$

c) $\frac{5x}{6}=\frac{8}{4}$

Answer 1

Resposta:

Explicação passo-a-passo:

 $\frac{x^{2}}{6} =6\\\\x^{2} =6.6\\\\x^{2} =36\\x=\sqrt[n]{36} \\x=6$

$\frac{2x+1}{x} =\frac{3}{4} \\4.(2x+1)=3.x\\8x+4=3x\\8x-3x=-4\\5x=-4\\x=-4/5$

$\frac{5x}{6} =\frac{8}{4} \\4.5x=6.8\\20x=48\\x=\frac{48}{20} =\frac{12}{5}$
