Задание по математике 35,36

Answer 1

$a + ( - 3.5) = 0.84 - 3.5 = - 2.66 \\ a + ( - 3.5) = 7.3 - 3.5 = 3.8 \\ a + ( - 3.5) = - 4.7 - 3.5 = - 8.2 \\ a + ( - 3.5) = 2 \frac{1}{6} - 3 \frac{1}{2} = 2 \frac{1}{6} - 3 \frac{3}{6} = - 1 \frac{2}{6} = - 1 \frac{1}{3} \\ \\ - 1.6 + ( - n) = - 1.6 - 4 = - 5.6 \\ - 1.6 + ( - n) = - 1.6 - 15 = - 16.6 \\ - 1.6 + ( - n) = - 1.6 - ( - 7) = - 1.6 + 7 = 5.4 \\ - 1.6 + ( - n) = - 1.6 - 1.5 = - 3.1 \\ - 1.6 + ( - n) = - 1.6 - ( - \frac{1}{3} ) = - 1.6 + \frac{1}{3} = - 1 \frac{3}{5} + \frac{1}{3} = - 1 \frac{9}{15} + \frac{5}{15} = - 1 \frac{4}{15}$
