Lúc đó cả hai bao nặng  là:

98,5 - 1,9 = 96,6 ( kg)

Coi bao đường thứ nhất lúc bớt đi là 1 phần thì bao đường thứ hai  là 3 phần như thế.

Vậy tổng số phần bằng nhau là :

1 + 3 = 4 ( phần )

Bao đường thứ hai nặng là :

96,6 : 4 x 3 = 72,45 ( kg)

                    Đ/S : 72,45 kg đường

CHÚC HOK TỐT NHÉ !

(x+y)-(x-y)=x+y-x+y=(x-x)+(y+y)=0+2y=2y

moi hok lop 6

(x+y)-(x-y)

=x+y-x+y=y+y=2y (phá ngoặc)

vậy (x+y)-(x-y)=2y

It will be a great joy or happiness for everyone if we can own a house designed by ourselves. A house in my dream is not necessarily a large house, as long as it fits my style and character. A house located on the outskirts of town will be very suitable for me to enjoy a serene life. It will be a two- storey house facing west-south side. Moreover, my house can not be lack of a large garden surrounded by thousands of different colors of flowers and fruits. I like it the most when having a breakfast or enjoying night views in my own garden. Simplicity is beauty, this explains why I would prefer an airy space rather than a well- equipped house. However, the house should have basic necessities in the kitchen and bathroom to serve all my demands in daily life. In addition, I will use bright color tones for the whole house, especially my bedroom to make it more spacious. My bedroom will be more perfect and ideal if it has a balcony where i could smell the fragrance from the garden as well as enjoy the sound of the birds in the morning. Besides, I also have an intention of having a small garage and storage. In conclusion, nothing but a suitable house for my lifestyles will fulfill my future dream.

Hello everyone! Today I'll tell you about my house. I live in a big house in the countryside and it is very beautiful. It has a living room, a kitchen, three bedrooms and two bathrooms. In the living room, there is a table, four chairs, a television and an air conditioner. My bedroom is very nice. There is a computer, a bed, a lamp and two pictures on the wall. And a bookshelf above the table, some teddy bears on the bed and a wardrobe. The kitchen has a refrigerator, a stove and a sink. Next to the kitchen is the bathroom. It has a shower, a washing machine and a tub. I love my house very much.

Sau khi bán thì còn lại số trứng là: 

\(1500-240=1260\)(quả) 

Số trứng còn lại nếu số trứng gà là \(5\)phần thì số trứng vịt là \(9\)phần.

Tổng số phần bằng nhau là: 

\(5+9=14\)(phần) 

Ngày hôm đó trại thu được số quả trứng vịt là: 

\(1260\div14\times9=810\)(quả) 

Ngày hôm đó trại thu được số quả trứng gà là: 

\(1500-810=690\)(quả)
