\(\Leftrightarrow\left(x-100\right)\left(\dfrac{1}{10}+\dfrac{1}{12}+\dfrac{1}{14}+\dfrac{1}{16}+\dfrac{1}{17}\right)=0\)
\(\Leftrightarrow x=100\) vì \(\left(\dfrac{1}{10}+\dfrac{1}{12}+\dfrac{1}{14}+\dfrac{1}{16}+\dfrac{1}{17}\right)\ne0\)
\(\Leftrightarrow S=\left\{100\right\}\)
giúp mik y đc ko ạ cám ơn rất nhiều ạ
Giúp mik 2 bài này vs ak!!! Cám ơn ạ!!!
Bài 3:
Ta có: a//b
nên \(x+y=180\)
mà \(2x-3y=0\)
nên \(\left\{{}\begin{matrix}x+y=180\\2x-3y=0\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}2x+2y=180\\2x-3y=0\end{matrix}\right.\)
\(\Leftrightarrow\left\{{}\begin{matrix}5y=180\\x+y=180\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}y=36\\x=144\end{matrix}\right.\)

1.what do you think about the environment in your town?
In my hometown , people are not aware of environmental protection, there are still many people who are unaware and throw their garbage out, besides, there are still people who pick up trash and throw it in the right place.
Every day on the news reports, the news is everywhere, saying phrases like melting ice, global warming, acid rain, global climate change or adding new lands to become industrial landfills. All are consequences of environmental pollution.
1. We decorate houses at Halloween.
2. John sometimes plays video games with his friends after school.
3. The fashion show starts at 8 p.m.
4. How do people prepare for Christmas?
5. How often do you go shopping?
6. The bus leaves at 10 a.m.

a) \(6x^2-8x=2x\left(3x-4\right)\)
b) \(21x^2y^7-12x^5y^3=3x^2y^3\left(7y^4-4x^3\right)\)
c) \(4x^2y-6xy^2=2xy\left(2x-3y\right)\)
d) \(24x^2y-18xy^2=6xy\left(4x-3y\right)\)
e) \(9x^2y^2+12x^2y-15xy^2=3xy\left(3xy+4x-5y\right)\)
f) \(x\left(x+y\right)+y\left(-x-y\right)=x\left(x+y\right)-y\left(x+y\right)=\left(x+y\right)\left(x-y\right)\)
g) \(3\left(x+y\right)+x\left(x+y\right)=\left(x+y\right)\left(x+3\right)\)
h) \(3x\left(x-y\right)-6y\left(y-x\right)=3x\left(x-y\right)+6y\left(x-y\right)=3\left(x-y\right)\left(x+2y\right)\)
