200 + 1 / 2-1 / 3 + 1 / 2 - ··· + 1 / 2-2003-1 / 3
1:2008 + 2:2008-3:2008 - ·· - 2008:2008 + 2008:2009

Denominator invariant numerator addition
1 / 2008 + 2007 / 2008 = 1, a total of 2008 / 2-1 = 1003
And 1004 / 2008 + 2008 / 2008 + 2008 / 2009
1 / 2008 +... 2008 / 2009 total = 1003 + 1004 / 2008 + 2008 / 2008 + 2008 / 2009 = 1005 + 1005 / 2008

Car a and car B drive from a and B. car a runs 80 kilometers per hour and car B runs 82 kilometers per hour. Car a starts 1.25 hours later and car B starts. After 1.5 hours, the two cars meet. How many meters are there between a and B?

80x1.25+(80+82)x1.5=343

In the first problem, we know that the solution of the equation 2-1 / 3 (A-X) = 2x about X is x = 1, and find the solution of the equation y + 4 / 30 plus 3y-2a / 2 = 4
If 1 / 6 (x + 2) = A-1 / 3 (x-1), a is more than 1 / 4 of X, find the value of X

The first problem: from the solution of the equation 2-1 / 3 (A-X) = 2x about X to x = 1, we can get: 2-1 / 3 (A-1) = 2 * 1A = 1, so for the Y equation y + 4 / 30 plus 3y-2 * 1 / 2 = 4, 4Y + 4 / 30 = 54y = 146 / 30y = 292 / 15, we can get: a = x * 1 / 4 + 1, so 1 / 6

A and B leave from a and B at the same time and meet at 36km from the midpoint after 3 hours. It is known that the speed ratio of a and B is 3:2. How many kilometers are there between a and B?

A: the distance between a and B is 360 km

After 7 / 3 is converted into a decimal, what is the number on the 1999 digit to the right of the decimal point? What is the sum of these 1999 digits

7 divided by 3 equals 2.3 3 cycles, so the 1999 bit is 3, and then the 1999 times 3 equals 5997

A and B two cars leave from two cities at the same time. After three hours, the two cars meet at a distance of 18km from the center. At this time, the distance ratio of a car to B car is
The ratio is 2:3. How many kilometers per hour does car a and car B travel? No one is allowed to find the answer from the Internet,

A travels less per hour than B: 18 × 2 △ 3 = 12 km
A's speed: 12 △ (3-2) × 2 = 24 km / h
B's speed: 24 + 12 = 36 km / h

In triangle ABC, if s triangle ABC = 1 / 4 (B & # 178; + C & # 178; - A ^ 2)

b²+c²-a²=2bccosA
S triangle ABC = 1 / 4 (B & # 178; + C & # 178; - A ^ 2) = 1 / 2bccosa = 1 / 2bcsina
∴cosA=sinA
∴tanA=1
∴A=45°

Someone rides a bicycle from place a to place B. he starts from place a and takes 20 minutes to complete two fifths of the journey. Then he speeds up,
Every minute is 60 meters more than before. After another 15 minutes, it is still 1.8 kilometers away from B. how many kilometers are there between a and B?
Primary school students can understand it

2/5÷20×15=3/10
60 × 15 = 900m = 0.9km
Another 3 / 10 of the whole journey, more than 0.9 km
Distance = (0.9 + 1.8) / (1-2 / 5-3 / 10) = 9 km

If the mean of data 1, 2, 2, X is the same as the mode, then x is equal to ()
A. 1B. 2C. 3D. 4

According to the meaning of the question: 5 + X4 = 2, the solution is x = 3, so choose C
