My favorite pet is a dog. I love dogs because they are cute and loyal to their owners. I have a dog at home, his name is Ki. Ki is a dog which I have been keeping for four years. It is a Poodle so it is really friendly. It has bushy and soft brown fur and glistening eyes. When I look at his big, beautiful eyes, I just melt like ice cream on a hot summer day. Ki takes pleasure in sniffing everything when he has nothing particular to do. Everyday, I give her some biscuits and milk in the morning, rice and meat in the afternoon. Whenever I go out in the evening, he always accompanies me like he wants to protect me. Ki seems to be one of my best friends, I love him very much!

Lời giải:

Áp dụng định lý Pitago: $AC=\sqrt{AB^2+BC^2}=\sqrt{3^2+4^2}=5$ (cm) 

Áp dụng tính chất tia phân giác:

$\frac{IA}{IC}=\frac{AB}{BC}=\frac{3}{4}$

Mà $IA+IC=AC=5$

$\Rightarrow IA=5:(3+4).3=\frac{15}{7}; IC=5:(3+4).4=\frac{20}{7}$ (cm)

Nếu thêm vào số lớn 27 đơn vị thì hiệu lúc đó là: 123 + 27= 150
Ta có sơ đồ:
Số bé:  ,___,___,
Số lớn: ,___,___,___,___,___,___,___,
                                   150     
Số bé là:
    150:(7-2)x2=60  

Lời giải:
Theo đề thì số kẹo của Hoa chia hết cho 5 nên số kẹo của Hoa có thể là $20$ hoặc $25$. Mà số kẹo của Hoa không chia hết cho $2$ nên số kẹo của Hoa là $25$ (chiếc)

 \(\dfrac{1}{3}\)  - |\(\dfrac{3}{4}\) - \(x\)| = 12

        |\(\dfrac{3}{4}\) - \(x\)| =  \(\dfrac{1}{3}\) - 12

       | \(\dfrac{3}{4}\) - \(x\)| =  - \(\dfrac{35}{3}\)

   Vì |\(\dfrac{3}{4}\) - \(x\)| ≥ 0 ⇒ - \(\dfrac{35}{3}\) ≥ 0 (vô lý)

Vậy không có giá trị nào của \(x\) thỏa mãn đề bài
