Answer 2

Explicação passo-a-passo:

$1) \sqrt{ \frac{49}{81} } + \sqrt{ \frac{1}{4} } = \\ \frac{ \sqrt{49} }{ \sqrt{81} } + \frac{ \sqrt{1} }{ \sqrt{4} } = \\ \frac{7}{9} + \frac{1}{4} = \frac{28 + 9}{36} = \frac{37}{36} \\ \\ 5) - 2 + 16 = 6x \\ 14 = 6x \\ x = \frac{14}{6} = \frac{7}{3} \\ \\ 3)4x - 30 = - 11x \\ 4x + 11x = 30 \\ 15x = 30 \\ x = \frac{30}{15} \\ x = 2 \\ \\ 6)2x + 10 = 3x \\ 2x - 3x = - 10 \\ - x = - 10 \: \: \: \: \times ( - 1) \\ x = 10$[/tex]
