Question

3/7умнож( - 0,6х ) = - 1,44

Answer 1

Ответ:

$\frac{3}{7} *(-0,6x)= -1,44$

$\frac{3}{7}*(-0,6x)= -(\frac{3*6}{7*10}x)= -(\frac{3*3}{7*5}x)= -\frac{9}{35}x$

$-\frac{9}{35}x= -1,44$

$x= -1,44 :(-\frac{9}{35} )$

$-1,44:(-\frac{9}{35}) =1\frac{44}{100}:\frac{9}{35}=1\frac{11}{25}:\frac{9}{35}=\frac{36*35}{25*9}=\frac{4*7}{5}=\frac{28}{5}=5\frac{3}{5}=5,6$

x=5,6

Ответ: х=5,6
