Giúp mìn đi :33

Nguyễn Lê Phước Thịnh · Accepted Answer

a: $\Leftrightarrow x-\dfrac{1}{5}=\dfrac{7}{11}\cdot\dfrac{1}{7}=\dfrac{1}{11}$

hay $x=\dfrac{1}{11}+\dfrac{1}{5}=\dfrac{5+11}{55}=\dfrac{16}{55}$

b: $\Leftrightarrow\dfrac{x}{25}=\dfrac{-21}{90}=\dfrac{-7}{30}$

hay $x=-\dfrac{175}{30}=-\dfrac{35}{6}$

c: $\Leftrightarrow x+\dfrac{7}{5}=\dfrac{4}{8}\cdot\dfrac{9}{27}=\dfrac{1}{6}$

hay $x=\dfrac{1}{6}-\dfrac{7}{5}=\dfrac{5-42}{30}=\dfrac{-37}{30}$

d: $\Leftrightarrow x:\dfrac{5}{11}=\dfrac{-24}{12}=-2$

hay x=-10/11

Câu trả lời:

a: $\Leftrightarrow x-\dfrac{1}{5}=\dfrac{7}{11}\cdot\dfrac{1}{7}=\dfrac{1}{11}$

hay $x=\dfrac{1}{11}+\dfrac{1}{5}=\dfrac{5+11}{55}=\dfrac{16}{55}$

b: $\Leftrightarrow\dfrac{x}{25}=\dfrac{-21}{90}=\dfrac{-7}{30}$

hay $x=-\dfrac{175}{30}=-\dfrac{35}{6}$

c: $\Leftrightarrow x+\dfrac{7}{5}=\dfrac{4}{8}\cdot\dfrac{9}{27}=\dfrac{1}{6}$

hay $x=\dfrac{1}{6}-\dfrac{7}{5}=\dfrac{5-42}{30}=\dfrac{-37}{30}$

d: $\Leftrightarrow x:\dfrac{5}{11}=\dfrac{-24}{12}=-2$

hay x=-10/11
