Answer 1

а) $\frac{0.7m - 1.3}{0.29 - 0.18n} = \frac{0.7 \times 2.1 - 1.3}{0.29 - 0.18 \times 3.5} = \frac{0.17}{ - 0.34} = 0.17 \div ( - 0.34) = - 0.5.$

б) $\frac{ {x}^{2} + 1.37}{3.1y - 0.17} = \frac{(5.3) {}^{2} + 1.37 }{3.1 \times 0.7 - 0.17} = \frac{29.46}{2} = 29.46 \div 2 = 14.73.$

Answer 2

Пошаговое объяснение:

$a) \frac{0.7m - 1.3}{0.29 - 0.18} \\ \\ \frac{0.7 \times 2.1 - 1.3}{0.29 - 0.18 \times 3.5} \\ \\ \frac{1.47 - 1.3}{0.29 - 0.63} = - 0.5 \\ \\ \\ \\ b) \frac{x {}^{2} + 1.37}{3.1y - 0.17} \\ \\ \frac{5.3 {}^{2} + 1.37 }{3.1 \times 0.7 - 0.17} = 14.73$
