The third sub question of the fifth question in the fifth grade classworkbook

Hungry after. "There is Yan Ruyu in the book, and there is a ** house in the book. ”

Reading is like a hungry person pounces on bread. This is right?

Triangular circumference = the sum of the three sides.

square centimeters) A: Its area is square centimeters.

This is the Beijing Normal University version, so please write the question on it.

Are you asking about the median? If yes, the question can actually be like this, according to the definition, the question has 7 numbers, that is, that is, the median is n4, then the average of the first four numbers is, that is, n1+n2+n3+n4= The average of the last four numbers is, again, that is, n4+n5+n6+n7=. The sum of the entire eight numbers n1 + n2 + n3 + n4 + n5 + n6 + n7 =

That is, n1 + n2 + n3 + n4) + that is, n4 + n5 + n6 + n7) is n1 + n2 + n3 + n4 + n5 + n6 + n7) = 49 (that is, n4).

Growing pains.

The pace of growth has come, and the growing pains have followed. It makes people shroud in melancholy all day long.

Why are you so careless, the uppercase letters of English are written in lowercase; Mathematics is either forgetting to add the decimal point, or the brain can't turn around; The same is true of language, what should not be wrong is always wrong. ......Grades are always not improving! "Since the beginning of my childhood, these kinds of words have always haunted me.

Sometimes it's my parents' criticism, sometimes it's my self-discipline, and sometimes it's my sister's sarcasm.

I also want to improve my grades, but I can't get my way. Either this subject missed, or that subject failed. These are things I never expected.

Who doesn't want to get a good score, but everyone's ability is different, and the effort is different, so the "fruit" of the harvest is also shriveled and full. That's why I can only say, "Do your best!"

Finish. Life is full of competition and grind – these are my words to comfort myself. But despite this, there are still a lot of worries that linger on me: as a student, I told myself that I couldn't get too bad grades; As a daughter, I told myself not to let my parents down; As an older sister, I told myself to give my sister a good example ......As a result, there is an increasing number of troubles.

But on the other hand, if I get a good grade so easily, wouldn't it be a great loss of its own meaning and people's desire to have it? When you think about it this way, there are a lot fewer worries. But there is another view formed in my mind - although there is some truth in the above statement, it is too naïve, a bit like saying that grapes are sour if you can't eat them.

If you don't work hard, good grades won't come to your door. So the orange draft, the troubles are still like a shadow, following me all the time. This may be a mediocre nuisance, but it is true that this should be the trouble that most students face.

The solution to this problem is to study, study, and learn again. "I've been annoyed lately, and I've been annoyed ......"I now finally understand that this song is actually a song about the helplessness and confusion that our teenagers show in the face of the troubles of studying. Growing pains are constantly coming, and I hope that we can withstand the "attack" of all troubles and learn to grow healthily in them!!

6*6+6*6-4=68

Answer: The area covered by two squares is 68

Solution: Covered area = area of two squares - overlapping area.

6*6)*2-4。。。6*6*2 is the area of the two cubes, and 4 is the overlapping area.

68cm Finally, remember to answer! Hope to help you solve this problem. If you still don't understand, please ask me! Kiss.

Covered area = area of two squares - overlapping area.

68cm, I hope to help you solve this problem.

6x6x2 = 72cm 72-4 = 84cm The area of the two squares - the area of the overlapping parts.

Set the time to go up the mountain x

All that's left is to solve the equations.

The distance is equal to the speed multiplied by the time.

Let the distance be x

Then the time to go up the hill is x, and the time to go down x is x

The total time is x

Solution x = 6 km.

It can be seen from the title.

Xiaoli score + Xiaolan score) 2=97

2 Xiaolan's score +4=194

Xiaolan score = 95 Xiaoli score = 99
