1. This building was built by the local people in the early 19th century.

2. The layout of this university is drawn by a famous French architect.

3. Ho Chi Minh Mausoleum can't be visited on Monday.

Số tiền mua là: 1800000:20.100=90000001800000:20.100=9000000 (đồng)

Tiền vốn để mua số hoa quả đó là 9000000−1800000=72000009000000−1800000=7200000 (đồng)

Gọi CTHH của chất khí đó là XO2 

ta có \(\frac{M_{XO_2}}{MO_2}=1,4375< =>\frac{Mx+32}{32}=1,4375=>Mx=14đvc\)

=> X là nito 

=> CTHH của chất khí đó là NO2

1. very interested in cooking
2.the same as it was last year
3.as tall as you
4.was bought by her father last week
5.was seen by him
Không biết có đúng không?

ko biếttttttttttttttttt

?????

x : (-7) . 4 = -5 . (-6)

x : -28 = 30

x = 30. ( -28)

x = -840

Vậy x=-840

_HT_

\(x:\left(-7\right)4=\left(-5\right)\left(-6\right)\)

\(x:\left(-7\right)=24:4\)

\(x:\left(-7\right)=6\)

\(x=6\left(-7\right)\)

\(x=\left(-42\right)\)

\(\left(x+5\right)\left(3x+27\right)=0\)

\(\Rightarrow\orbr{\begin{cases}\left(x+5\right).0=0\\0.\left(3x+37\right)=0\end{cases}}\)

\(\Rightarrow\orbr{\begin{cases}x+5=0\\3x+27=0\end{cases}}\)

Trường hợp 1.

 \(x+5=0\)

\(x=0-5\)

\(x=\left(-5\right)\)

Trường hợp 2. 

\(3x+27=0\)

\(3x=0-27\)

\(3x=\left(-27\right)\)

\(x=\left(-27\right):3\)

\(x=\left(-9\right)\)

Vậy \(x\in\left\{-5;-9\right\}\)
