The sum of two integers is 52, the greatest common factor is 4, and the least common multiple is 144. What are these two numbers?

The sum of two integers is 52, the greatest common factor is 4, and the least common multiple is 144. What are these two numbers?


52÷4=13
144÷4=36=4×9
What are the two numbers
4×4=16
4×9=36



The expression of the function is that the line y equals KX plus B is parallel to the line y equals negative three x plus two and passes through the point coordinates (1,6)


If the function y = KX + B is parallel to y = - 3x + 2, then k = - 3. That is, the function y = - 3x + B passes through the point (1,6). Therefore, 6 = - 3 + B, B = 9. That is, the analytic expression of the function is y = - 3x + 9



I want a cartoon composition for unit 1! 400 words
Good ~ is that "false illiterate" cartoon, asked to write a composition. Can also be other cartoons, as long as you write a cartoon composition is good: - O


Hua Junwu, a famous cartoonist, once drew a cartoon, which profoundly exposed those who only wanted their own convenience without social morality. That cartoon gave me a strong shock and always appeared in my mind
You see, there are a lot of people in the waiting room. A woman holding her child anxiously looks around. She is wrapped in thick cotton padded clothes and braves the cold wind to get on the bus. She is sweating and panting. From the crowd, she finally finds the stop sign of "where mother and son get on the bus", Unexpectedly, there was already a middle-aged man standing under the stop sign. She thought strangely: This is clearly where mother and son get on the bus. How could he Just as she was thinking about it, three more people came. She quickly said, "is this the place where mother and son get on the bus? Could you please give me some place? It's inconvenient for me to hold my baby!" however, the four men stood there with ease, ignoring her, pretending to be nothing. The woman had to stand aside
Are the four illiterate? Are they all illiterate? No, they are well-dressed and have ink in their stomachs. They can't be illiterate. They just want to get the convenience of getting on the bus, but they let the mother and son who really should enjoy the preferential treatment of getting on the bus down to one side. They closed their eyes because they didn't dare to look at the bright words on the bus stop and the mother and son. Their hearts were no longer pure, Their moral character has long been filthy
In fact, as long as we pay a little attention, there are many such things around us
Every spring, the green grass in the park pokes its head out of the soil. The light color and faint grass fragrance always make people feel relaxed and happy. There is a sign beside the grass, which says: cherish life, protect grass! But some people, in order to take less steps, Step your feet over the lovely grass. Don't they know how many lives will be killed in one step? Can't they see the warning signs? No, they are "pseudo illiterate"!
This kind of false illiteracy is everywhere, which is the main cause of moral decline in our society. These people's moral character and behavior are shameful! A civilized society needs everyone's civilized behavior to care for, and social morality needs every citizen to abide by. Especially in today's market economy, our society is more eager for everyone to promote virtue, Pay attention to morality and abide by public morality. Let our society blow the wind of civilized virtue in every corner!
I hope "pseudo illiteracy" will disappear from the world earlier!



There are 2000 chickens and 1 / 5 ducks in the farm


2000*1/5+2000=2400



What is the one digit number of 2 to the power of 2013?


Find the rules: 1 2
2 4
3 8
4 6
5 2
6 4
.
Four one cycle, 2013 = 4 * 503 + 1, so the number of 2 to the power of 2013 is 2



Xiaohong has 10 banknotes with a face value of 1 jiao, 2 jiao and 5 jiao, totaling 2 yuan and 6 jiao. How many banknotes can Xiaohong have with a face value of 5 jiao at most?


Let 1 corner x sheet, 2 corners y sheet, 5 corners Z sheet
x+y+z=10
x+2y+5z=26
y+4z=16
y=0,z=4
Xiaohong has 10 banknotes with a face value of 1 jiao, 2 jiao and 5 jiao, totaling 2 yuan and 6 jiao, so Xiaohong has at most 4 banknotes with a face value of 5 jiao
2 jiao 0, 1 jiao 6
If there are no 2-jiao's, 3-jiao's, 4-jiao's and 3-jiao's



Find the first n terms and Sn of sequence 1 * 2 / 2,2 * 3 / 2,3 * 4 / 2,4 * 5 / 2


Sn=2/(1×2)+2/(2×3)+2/(3×4)+2/(4×5)+...+2/[n(n+1)]
=2[1/(1×2)+1/(2×3)+1/(3×4)+1/(4×5)+...+1/n(n+1)]
=2[1-1/2+1/2-1/3+1/3-1/4+1/4-1/5+...+1/n-1/(n+1)]
=2[1-1/(n+1)]
=2n/(n+1)



Take (X-Y) and (a + b) as a factor and merge the similar terms
1. The square of 3 (X-Y) - 7 (X-Y) + 8 (X-Y) + 6 (X-Y) + 1, 2, 4 (a + b) + 2 (a + b) - the zero power of 3 (a + b) - 7 (a + b) + 2 (a + B)


1、11(x-y)^2-(x-y)+1 2、-5(a+b)^2+(a+b)+2



The application of linear equation of one variable in the first grade mathematics of junior high school
1. The distance between a and B is 416 kilometers. A car goes from a to B for 32 kilometers per hour. Half an hour after the car leaves, one or two motorcycles drive from B to a, and the speed is 1.5 times that of the car. How many hours can the motorcycle meet the car?
2. The distance between a and B is 15 kilometers. Team a travels 5 kilometers per hour. Team a and B start from a and B at the same time and walk back to each other. After a few hours, they are 60 kilometers apart?
3. It is known that the distance between a and B is 120 km, and the speed of B is 1 km faster than that of a per hour. A starts from a for 2 hours, and B starts from B, and then faces a for 10 hours,
4. A starts from place a by bike and drives to place B at the speed of 12 km / h. After 15 minutes, B starts from place B by bike and drives to place a at the speed of 14 km / h. when they meet, B has exceeded the midpoint of 1.5 km, so as to find the distance between a and B
5. The distance between a and B is 20 kilometers. A and B start from a and B at the same time and face each other. Two hours later, they meet on the way. After meeting, a returns to a immediately, and B still advances to A. when a returns to a, B leaves a for 2 kilometers. What's the speed of the two?
All of them should be written according to the format of grade one,
