[tex]( \frac{3}{7} x + \frac{5}{14} x - \frac{1}{2} x) \div ( - \frac{1}{35} ) = ( \frac{6}{14} x + \frac{5}{14} x - \frac{7}{14} x) \div ( - \frac{1}{35} ) = \frac{4}{14} x \div ( - \frac{1}{35} ) = \frac{2}{7} x \div ( - \frac{1}{35} ) = - \frac{2 \times 35}{7} x = - 10x = - 10 \times 0.1 = - 1[/tex]

Пошаговое объяснение:

(3/7х+5/14х-1/2х):(-1/35)=

=(6/14х+5/14х-7/14х):(-1/35)=

=4/14х:(-1/35)=2/7х•(-35/1)=

= -10х= -10•0,1= -1
