Hello, landlord
The total expenditure of Xiaoxiaojia's family in 2008 is x yuan
40％x+15％x=7700

Hope to help you, do not understand, please ask

During the Spring Festival, Xiaohong's food expenditure is 600 yuan and tourism expenditure is 1200 yuan, accounting for 60% of the total household expenditure?

{(600+1200)/0.6}-1800=1200

In 2008, the expenditure on food accounted for 35% of the total expenditure of the family, and the expenditure on continuing education accounted for 10% of the total expenditure. The total expenditure of the two items was 6750 yuan. How much was the total expenditure of the family?

6750 divided by 45% quotient

The expenditure of Xiaoxiao's family, culture and education accounts for 10% of the total monthly expenditure, and the expenditure on food accounts for 50% of the total monthly expenditure
In China, the expenditure on food is 1000 yuan more than that on culture and education?
I have an urgent need

1000/(50%-10%)=2500

The output of Jinxue group increased by 20% every year compared with the previous year. The output in 2009 increased by 2400 tons compared with that in 2008
Use formulas, not equations

2400 / 20% equals 12000 12000-2400 equals 9600 9600 * 0.2 equals 1920 9600-1920 equals 7680 in 2007

Uncle Wang's apple production in 2009 was 2400KG, and the price per kg was 2.5 yuan; the apple production in 2010 was higher than that in 2009
Uncle Wang's apple production in 2009 was 2400KG, and the price per kilogram was 2.5 yuan. The apple production in 2010 increased by 20% compared with that in 2009, and the price per kilogram was 2.2 yuan. Compared with two years, which year had more income?

In 2009, it was 2400 × 2.5 = 6000 yuan
10 years is 2400 × (1 + 20%) × 2.2 = 6336 yuan
So more than 10 years

The first snow in 2009
Mainly around the use of this snow, 500 words, well written, I will take him as the best answer

"Look, it's snowing!" I was attracted to the corridor by the sound. Looking out, it's really good. The small snowflakes are falling slowly. My heart can't help but feel a sense of joy. I hope it can bring us a real heavy snow. Soon, the city has been covered by the gentle snowflakes. Every snowflake is gently

About the first snow in 2009!
Urgent! No less than 600 words, 1

With the "creak" and "creak" sound of the bed board, I got up and glanced out of the window. I saw some strange white. After a close look, I knew that the snow had fallen quietly
I've been looking forward to this snow for a long time, waiting for it to moisten everything. To tell you the truth, I'm also picky about snow. In yongxue Lianju, it says, "it's better to sprinkle salt in the air than catkins in the wind." I think it may be the snow in the south of the Yangtze River, which is delicate. The snow in the South loves to make trouble with the rain, and it can't stay in the world forever, But it is the true portrayal of the University in the north
The snow comes clean, without reservation to release its accumulated energy. The snow is the authentic northern snow. Such as the northern scenery, thousands of miles of ice, thousands of miles of snow, with a kind of bold and unconstrained. When the snow comes, the world is like a piece of white paper. Somehow, maybe Taiyang doesn't want to participate in the white feast, until more than 10 am, the sun didn't appear, and was blocked in the white
I have heard some elders say that after the winter solstice, in 1919, there was a saying that "don't do anything in 1929, walk on the ice in 3949..." Although it's not 1929, it's also cold. But in the heavy snow, I don't feel the chill that I can't get rid of. Instead, I'm excited. In the snow, we run and laugh. In our laughter, the snow is getting bigger and bigger. The snow is falling straight and fast. It's more and more dense and thicker on the ground, like weaving a big net, I don't know why I think so. Maybe I want the white snow to enrich my life
After school, walking on the way home, in the weak light, the snow reflected dazzling white light, flickering, continuous, at this time, I can really understand the crystal clear snow, looking at the transparent snow, I can't even bear to step on them
Anyway, I always feel that this snow is different from other times, and I can't put it all into this paper

2004 * 20032002-2002 * 20032004 simple operation

2004×20032002-2002×20032004=2004×（20030000+2002）-2002×（20030000+2004）=2004×20030000+20004×2002-2002×20030000-2002×2004=（2004×20030000-2002×20030000）+（2004×2002-2002×2004）=2004×200...

Simple operation: 1.993 * 1993000 + 19.92 * 199200-199.3 * 19920-1992 * 1991 =?

1.993×1993000+19.92×199200-199.3×19920-1992×1991
=1993×1993+1992×1992-1993×1992-1992×1991
=(1993-1992)×1993+(1992-1991)×1992
=1993+1992
=3985
