Question

Va rog cele cinci ecuatii!

Answer 1

Răspuns:

In fotografie.

Answer 2

Răspuns:

$-7=-\frac{w}{6}$

$(-7)6=-w$

$-42=-w$ inmultim cu -1

$w=42$

$15=\frac{3}{7} b$

$15*7=3b$

$b=\frac{105}{3}$$b=35$

$-0,(6)=\frac{9}{5}$

$-\frac{6}{9} =\frac{n}{5}$

$-\frac{2}{3} =\frac{n}{5}$

$(-2)*5=3*n$

$n=-\frac{10}{3}$

$n=-3,(3)$

$\frac{m}{2,6}=-5$

$m=(-5)*2,6$

$m=13$
