My uncle owns a small farm . He has a lot of chickens there. He sells eggs and chickens. Every summer, during the holidays, I go to his farm and help him. I feed the chickens and collect and clean the eggs. It is very interesting. My uncle’s hens are rather noisy. They are very useful because they lay eggs, but I don’t like them very much. I prefer the baby chickens and the cocks.

Let x be the number of the chickens

 45 -x is the number of the rabbits

We have: 2x + (45-x)4 = 140

 And then, we solve for x

2x + 180 - 4x = 140

180 - 2x = 140

2x= 40

x= 20

Therefore, the number of rabbits: 45 - 20 = 25

Rabbits: 25

Chickens: 20

3. Thank you for your letter. It’s very interesting to know about schools in the USA. I think schools in Vietnam are a little different. Vietnamese students usually wear school uniform. Classes start at 7 o’clock each morning and end at 11.15 in the afternoon. Students have a thirty-minute break after three periods. At break, many students play games. Some go to the canteen and buy something to eat or drink. Others talk together. Our school year lasts for nine months, from September to May. Then we have a three-month summer vacation.

A. True or false ( 1 pt )

1.      Schools in Vietnam are the same as schools in the USA.                   ____F____

2.      Vietnamese students do not usually wear school uniform.                ____F____

3.      Classes last from seven to a quarter past eleven.                                ____T____

4.      Most students go to the canteen at break.                                             ____F____
