Obs *Com o cálculo*

Answer 1

Explicação passo-a-passo:

A)

$2x > 3 \\ x > \frac{2}{3} \\ x > 1.5$

B)

$8x \geqslant - 5 \\ x \geqslant \frac{ - 5}{8} \\ x \geqslant - 0.625$

C)

$x - 4 \leqslant 5 \\ x \leqslant 5 + 4 \\ x \leqslant 9$

D)

$\frac{a}{2} < 7 \\ a < 7 \times 2 \\ a < 14$

E)

$3z - \frac{1}{2} > \frac{1}{4} \\ 3z > \frac{1}{4} + \frac{1}{2} \\ 3z > \frac{3}{4 } \\ z > \frac{3}{4} \times \frac{1}{3} \\ z > \frac{3}{12} \\ z > 0.25$
