Câu a:

x + 1/2 = 3/4

x = 3/4 - 1/2

x = 3/4 - 2/4

x = 1/4

Vậy x = 1/4

Câu b:

x - 3/2 = - 2/5

x = - 2/5 + 3/2

x= - 4/10 + 15/10

x = 11/10

Vậy x = 11/10

Câu c:

-2/3 = x/-9

x = -2/3 x (-9)

x = 6

Vậy x = 6

Câu d:

(x - 1/2)(x+ 5/3) = 0

x - 1/2 = 0 hoặc x + 5/3 = 0

x - 1/2 = 0

x = 1/2

x + 5/3 = 0

x = -5/3

Vậy x ∈ {-5/3; 1/2}

Câu a:

-2/3 + 3/3 = 1/3

Câu b:

13/8 + -5/8 - 3/4.12/7

= 13/8 - 5/8 - 9/7

= 1 - 9/7

= 7/7 - 9/7

= -2/7

Câu c:

3/13.(-5/7) + 3/13.(-2/7)

= 3/13.(-5/7 - 2/7)

= 3/13.(-1)

= - 3/13

Câu d:

4/11 - (7/16 + 37/11)

= 4/11 - 7/16 + 37/11

= (4/11 - 37/11) - 7/16

= -33/11 - 7/16

= - 3 - 7/16

= - 48/16 - 7/16

= - 55/16

My favourite means of transport is bike. A bike is small, light, and very convenient. I often use it to go to school or for a short trip with my friends. The best thing about a bike is that it’s eco-friendly. It doesn’t use any fuel, so it helps reduce air pollution and protect the environment. I really like riding my bike because it keeps me healthy and helps me save time. I don’t have to wait for the bus or worry about traffic. Most importantly, riding my bike makes me feel free and relaxed.

Topic 1: My favourite transport is the motorbike. It is fast and convenient for navigating through city traffic. I use it daily to go to work and visit friends. The feeling of freedom when riding is amazing. It is also relatively cheap to run and easy to park. I highly recommend it for urban living.

Topic 2: Hi [Friend's Name], How are you? There's a new action movie called 'The Chase' out this weekend. It looks great! Want to go watch it together on Saturday evening at 7 PM at the Mega Cinema? Let me know if you can make it. Hope to see you soon, [Your Name]

Topic 3: I would love to join the Holi festival in India. It's known as the 'Festival of Colors'. People throw colored powders and water at each other, dance, and celebrate the arrival of spring. The atmosphere looks incredibly joyful and vibrant. It seems like a unique and unforgettable experience to participate in such a lively celebration.

a) Ta có :

AB=AM+MB

hay MB=AB-AM

MB=6-3=3 (cm)

b) Điểm M là trung điểm của đoạn thẳng AB vì:

+Điểm M nằm trên đoạn thẳng Ab

+Điểm M năm giữa hai điểm A và B (AM=MB=3 cm)

a: Trên đoạn AB, ta có: AM<AB

nên M nằm giữa A và B

=>AM+MB=AB

=>MB=6-3=3(cm)

b: M nằm giữa A và B

mà MA=MB(=3cm)

nên M là trung điểm của AB
