Answer 1

bn nào trl mk tích nhé

Answer 2

ko ai trl mk à

Answer 3

\(6,35x+3,65x=30\Leftrightarrow x\left(6,35+3,65\right)=30\)

\(\Leftrightarrow10x=30\Leftrightarrow x=3\)

Answer 4

mà mấy bn trl thì tích cho mk vs nhé

Answer 5

\(\dfrac{635}{100}\times x+x\times\dfrac{365}{100}=30\Leftrightarrow\dfrac{635x+365x}{100}=30\Rightarrow x=\dfrac{30\times100}{635+365}=3\)

Answer 6

Giải

\(6,35\) * \(x+x\) * \(3,65=30\)

\(x\) * \(\left(6,35+3,65\right)=30\)

\(x\) * \(10=30\)

\(x\)         \(=30:10\)

\(x\)         \(=3\)

Answer 7

\(6.35\cdot x+x\cdot3.65=30\)

\(\Leftrightarrow10x=30\)

hay x=3
