Answer 1

Resposta:

c. $\frac{4}{11}$

Explicação passo-a-passo:

$\frac{m+n}{3m-2n} = \frac{1}{4} \\\\\left \{ {{m+n=1} \atop {3m-2n=4}} \right. \\\\m = 1-n => m= 1 -(-\frac{1}{5}) => m= \frac{6}{5} \\3*(1-n) - 2n=4 => -5n=1 => n=-\frac{1}{5} \\ \frac{m+2n}{2m+n} = \frac{\frac{6}{5} + 2 * (-\frac{1}{5}) }{2 * (\frac{6}{5})+(-\frac{1}{5})} = \frac{\frac{4}{5} }{\frac{11}{5} } = \frac{4}{11}$
