Bài giải

Gọi số vở của anh Hải là \(x\) (quyển).

Trung bình cộng số vở của 3 anh em là:

\(\frac{30 + 30 + x}{3}\)

(quyển)

Theo đề bài, anh Hải có nhiều hơn trung bình cộng 8 quyển, ta có:

\(x = \frac{30 + 30 + x}{3} + 8\)

Giải:

\(x = \frac{60 + x}{3} + 8\) \(3 x = 60 + x + 24\) \(3 x = x + 84\) \(2 x = 84\) \(x = 42\)

It was a hot Friday afternoon, and Class 7A didn’t feel like studying. Ms. Green was writing math problems on the board, but no one was paying attention.

At the back of the room, Jack was secretly eating chips. Emma was passing funny notes to her friends. In the middle row, Max made a paper airplane and threw it — it landed right on Ms. Green’s head!

The class burst out laughing. Ms. Green turned around slowly. “Alright,” she said, “if you want to play, let’s play a game. But…” she smiled, “the winner will have extra homework!”

Suddenly, the room became silent. Everyone opened their books and started working faster than ever.

From then on, Class 7A still liked to joke around, but they never forgot the day their “naughty fun” almost doubled their homework.
