Đề bài:Cô Lan mua 2 quả táo và 3 quả cam với giá 84000 đồng. Cô hoa mua 4 quả táo và 5 quả cam với giá 150000 đồng. Tìm giá của 1 quả táo.
Bài giải:
Ta thấy:
2 quả táo + 3 quả cam = 84 000 đồng
4 quả táo + 5 quả cam = 150 000 đồng.
Ta thấy 4 chia hết cho 2.Do đó,ta có thể rút 2 quả táo => 0 quả táo và 4 quả táo => 2 quả táo.
Khi đó,ta có:
0 quả táo + 3 quả cam = 84 000 đồng
2 quả táo + 5 quả cam = 150 000 đồng.
Theo cách trên,ta có giá 1 quả cam là:
84 000 : 3 = 28 000 (đồng)
Gía của 5 quả cam là:
28 000 x 5 = 140 000(đồng)
Gía của 2 quả táo là:
150 000 - 140 000 = 10 000(đồng)
Giá của 1 quả táo là:
10 000 : 2 = 5000 (đồng)

Nhanh nha mik đã dịch nên mn nhanh lên một chút nha !
giải : 1 cái bút giá là : 3,1 x 3 = 9,3 ($)
5 cái thước kẻ giá là : 3,1 x 5= 15,5 ($)
3 cái bút giá là : 9,3 x 3= 27,9 ($)
Trung bình cộng của 5 cái thước kẻ và 3 cái bút là : (15,5 + 27,9) :2 = 21,7
Vậy trung bình cộng của 5 cái thước kẻ và 3 cái bút là 21,7

Read the following passage and answer the questions
Ballpoint pen is a pen that has, as its name says, ball at its point which rotates when dragged across the writing surface and leaves behind ink that comes from the reservoir of the pen. Ball at the point can be of different diameter and can be made of brass, steel, or tungsten carbide. It is today the most widespread writing instrument and has literally changed the way we write.
Trying to invent a pen which can write on leather, a tanner John J. Loud invented the first ballpoint pen and patented it in 1888 in America. This pen had a small steel ball which was placed so it could not fall out nor fall in but it still could rotate freely. This invention was not commercially viable and could not be used for writing. Because of that patent lapsed in time.
Who invented the first ballpoint pen?
Đáp án là: John J. Loud invented the first ballpoint pen.
