1) I am happy to hear that you are in Ho Chi Minh City.

2) This time how about going to the Exhibition of Modern Art.

3) It is 8 o'clock on Saturday morning in the Arts Centre.

4) Let's meet at 7.3 outside the centre.

\(2\left(x+1\right)=\left|-10\right|\)

\(2x+2=10\)

\(2x=10-2\)

\(2x=8\)

\(x=8:2=4\)

a) 25-(15-19+13)+(12-18+10)

 = 25-15+19-13+12-18+10

=20

b)(53-76)-[-76-(-53)]

=53-76+76+53

=106

\(5^{20}:\left(5^{15}\cdot6+5^{15}\cdot19\right)\)

= \(5^{20}:5^{15}\cdot6+5^{20}:5^{15}\cdot19\)

= \(5^5\cdot6+5^5\cdot19\)

= \(3125\cdot6+3125\cdot19\)

= \(18750+59375\)

= \(78125\)

What is in the kitchen?

\(\dfrac{-9}{x}=\dfrac{-3}{\dfrac{4}{49}}\)

<=> \(\dfrac{-9}{x}=\dfrac{-147}{4}\)

<=> \(-9\cdot4=-147\cdot x\)

<=> \(-36=-147\cdot x\)

\(x=\dfrac{-36}{-147}=\dfrac{36}{147}\)

1) Where do we live?

2) Where is the museum?
