Answer 1

Ответ:

$2) \: \: \: - 19 + 46 = 46 - 19 = 27 \\ 3) \: \: \: - 7.2 - ( - 5.8) = - 7.2 + 5.8 = - 1.4$

$4) \: \: \: - 4 \frac{3}{4} \times ( - 2 \frac{6}{19} ) = - \frac{19}{4} \times ( - \frac{44}{19} ) = \frac{44}{4} = 11$

$5) \: \: \: 4.08 \div ( - 1.2) \div ( - 11 \frac{1}{3} ) = - 3 \frac{2}{5} \div ( - 11 \frac{1}{3} ) = - \frac{17}{5} \div ( - \frac{34}{3} ) = \frac{17 \times 3}{5 \times 34} = \frac{3}{10} = 0.3$

$6) \: \: \: - x - 5 \frac{3}{14} = - 2 \frac{2}{7} \\ - x = - 2 \frac{2}{7} + 5 \frac{3}{14} \\ - x = 2 \frac{13}{14} \\ x = - 2 \frac{13}{14}$
