王月同学考试时,开始只考了语文、数学、英语三科,平均分是84分,后来补考了体育,体

王月设答对X道,则答错(20-X)道
8X-5(20-X)=134
8X-100+5X=134
13X=234
X=18
设李响答错X道,答对(20-X)道
8(20-X)-5X=139
160-8X-5X=139
13X=21
X=21/13
P.S第二问的数字是不是打错了?
不可能出现分数啊

只能ABC里面没有的字!你用全拼打一定有的!

1、设王月从A地到B地共用X分钟,那么
(1/2)X*1+(1/2)X*0.8=60
得出 X=200/3
2、设X小时后两船相遇,那么
26*X+17*X=1075
得出：X=25
3、两人开始到第二次相遇,共走了3个AB的路程,所以
AB两地的路程=（4*4.5+4*3）/3=10KM

55555555555555555555555555555555555555

解法如下：
四个人一共可节省：38×(1-0.88)=38×0.12=4.56元
平均每人可节省：4.56÷4=1.14元
总的算式是：38×(1-0.88)÷4=1.14元
希望能够帮到你~~

Dear Emma,
I am very happy to receive your letter. That's really make me excited. Because the letter is from so far away!
Now I am sitting and writing the letter for you. From your letter I knew that you are a student in a high school there in California. I really envy that the beautiful beach that you guys have!I am a student,too.Here in Shanghai.As you know, Shanghai is a very mondern city. However, we don't have the nice beach as you do.Schools here are not as fun as yours.We have much pressure since each of us wanna go the best universities.I wanna go Fudan university to study East Asian.I know you are going to take the SAT, how is your study? Are they tough?
Which college are you going to apply for?Have you decide what major are you going to study?
Please send my warm greetings to your parents.
I am looking forward to your reply.
Regards,
Liyue

古代传说中的一种神珠 [supernatural pearl]

Hi!I'm WangYue.I'm 19 years old.My hobby is singing and dancing.I am a happy girl.I like English very much.Because it is fun.There are there people in my family.My father,my mother and I.I love them very much.This is me.嗨!我叫王月.今年19岁.我的爱好是唱歌,跳舞.我是一个快乐的女孩.我非常喜欢英语,因为它很有趣.我家有三口人.他们是爸爸,妈妈和我.我很爱他们.这就是我.【可能不够100词,你自己随便加点吧!】

0.8+1=1.8
1.8/2=0.9
60/0.9=200/3分

士别三日当刮目相看

every thing is my false,i hope you could forgive me,my loving WANGYUE.

设正确的数为X
10X-X=10.8
解得X=1.2
或者0.1X-X=10.8
X=-12

(78.5+81+79.5)/3

10X-5*（15-X）=120,
15X=195,
X=13（题）

82.2 总分少算9分,平均分少算9/45=0.2分
12 60-（60X1.2)/1.5

设每瓶饮料价钱为X
3X+1=5X-5
6=2X
X=3
他带了10块钱

水费：2×3×3.8+2.4×5=34.8元
（2.4是8.4-2×3）

3瓶多1元,买5瓶差5元,多出5-3=2瓶,多用了1+5=6元,可见每瓶3元,他带了10元钱.

以上三数之和,应该是三人成绩之和的两倍.再除2,就是三人成绩之和.
三人之和-两人之和,就是另外一人的成绩了.分别算三次,就可以算出三人的成绩

设：他全答对了.
25-1=24道
24*4=96分
96-81=15分
15/（4+1）=3道
答：他答错了3道.
