Environmental pollution has become a controversial issue that puts severe pressure on our rhythm of life. The pollution on Earth has reached such an alarming level that immediate involvement from governments and individuals collaboration now are of great importance. First and foremost, industrial activities are considered to be the main cause for air pollution. Along with global industrialization, the burning of fossil fuels, motor vehicles and factories are contaminating the air by their emission of harmful fumes. In the second place, pervasive deforestation for land use, overuse of fertilizers and the dumping pollutants such as plas or non- biodegradable packing in the ground has affected the ecosystem and led to soil pollution. This puts bad long- term effects on vegetation and soil fertility. Serious attempts to relieve the effects of pollution and preserve the environment need to be made as soon as possible. Governments can monitor the exhaust purification process of large factories so that they can prevent dangerous exhaust from the environment. Moreover, stricter regulations and laws against forest exploitation can help preserve a pristine environment. Individuals should be responsible and raise awareness for the protection of the environment. In conclusion, pollution has increasingly become a threat to the globe, directly affecting our life and for the sake of the environment and all citizens around the world, we should work hand in hand to protect our friendly house- the earth.

là ẩn dụ

ô kê la chx?

đó nha

Gọi ba số lẻ liên tiếp là:

x, x + 2, x + 4

trong đó x là số lẻ nhỏ nhất.

Trung bình cộng của ba số lẻ là:

Do đó, tổng của ba số là:

x + (x + 2) + (x + 4).

Rút gọn:

Tổng = 3x + 6

Trung bình cộng của chúng là:

Rút gọn:

TBC = x + 2  

Theo đề bài, trung bình cộng bằng 253. Ta có phương trình:

x + 2 = 253

Giải phương trình:

x = 253 - 2 = 251

Ba số lẻ liên tiếp là:

x = 251,     x = 253,     x + 4 = 255

Tính trung bình cộng của 251, 253, và 255:

Tổng ba số là:

251 + 253 + 255 = 759

Trung bình cộng:

Vậy kết quả hoàn toàn chính xác.

Ba số lẻ liên tiếp cần tìm là:

we are having salad for lunch, so we are not very hungry. Học tốt nha

"lành" nha bạn

Là điệp ngữ nha bạn

Ở từ nhà nào, em vẽ
