The distant geese are in autumn twilight, and the blue water reflects the smoke.

This palindromic poem, read backwards and backwards, is like flowing water, logical and rare. And the artistic conception in the poem is far-reaching and intriguing: the autumn colors are thousands of miles, the twilight is heavy, the smoke and haze reflect the water, the blue waves are long, a lonely goose, the wings of the goose reflect the afterglow of the setting sun, flying towards the distant horizon.

The ancient trees in the border city reflect the afterglow of the setting sun, and the covenant looks bleak and desolate. On the other side of the mountain, from time to time the wailing ...... of the lonely goose is crossedWhat a wonderful picture of sad autumn!

Haze, twilight, glow, ancient trees. Discovery: The meaning has not changed much! The meaning is similar to the meaning of reading!!

9 places. Smoke, Xia, Twilight, Geese, Ridges, Hui, Border Cities, Ancient Trees".

If each basket of apples is x kg, then each basket of pears is x + 20 kg.

25x+（x+20）*60=2645

x = 17 kg for a basket of apples and 37 kg for a basket of pears.

Assuming that each basket of apples weighs x kg, each basket of pears weighs x + 20 kg.

25x+（x+20）*60=2645

25x+60x+1200=2645

85x=2645-1200

85x=1445

x=17So, apples are 17 kg per basket, and pears are 17 + 20 = 37 kg per carton.

If the original Yi Nian Ye Cang is x tons, then the original person of A will shout 3x tons.

3x+80=（x+100）*2

3x+80=2x+200

3x-2x=200-80

Solve the first field x = 120

Solution: There were x tons of potatoes in the B warehouse.

A has 3x tons.

Column touches hands to celebrate the equation with a smile and shake:

3x+80=（x+100）*2

3x+80=2x+200

3x-2x=200-80

x=120

Original toothpaste cross-sectional area =

Modified toothpaste cross-sectional area =

Change in cross-sectional area due to change = square centimeters.

Increase the volume of toothpaste used per person per day = 2 * cubic centimeters.

Over the course of a year, brushing my teeth once a day for 365 days is counted as using more cubic centimeters.

x+y=8y+z=12

x+z=10

Add up the above three formulas and see.

x+y+z）×2=8+12+10 = 30x+y+z =15

If you use the proportions to be;

Untie; Set an average of x kilometers per day.

20-2）x=

18x =112

x = 6 and 2 9

Answer; On average, 6 and 2 9 kilometers are repaired per day.

2002 and 2005/2004 2004/2005 8/3 16 800 The square is larger than the pentagram and the star is larger than the triangle.

If you're in the sixth grade, you'll have to go back. People's Education Edition 6th Grade Volume 1 "Winter Vacation New Time and Space" p41 Using the above methods, can you calculate the following questions? The answer is, c c a a b a d 2,3

2. A triangle with a pentagram square.

The distance between the two cities is x kilometers.

x/100=x/120+1

Solution, x = 600 km.

So, the distance between the two cities is 600 kilometers.

== cubic centimeters) This is the area of the small circle.

cubic centimeter) This is the area of the great circle.

Let the radius r of the large circle and the radius r of the small circle;

then simplified: r 2-r 2=20

and r = so (ie.

r=4，r=6

From s = r 2, we can see that the radius of the great circle is a multiple of the radius of the small circle, then the area of the great circle is a multiple of the area of the small circle.

So the area of the small circle is cubic centimeters.

The area of the great circle is: cubic centimeters.
