这个方阵的行数
=8+7-1
=14
这个方阵的列数
=6+9-1
=14
这个方阵的总人数
=14*14
=196人

解 因为都是整吨数
3.3÷0.8不为整数
所以王青家没超过10吨
设 王青家用水X吨 李哲Y吨
所以
(Y-10)*0.8+(10-X)*0.45=3.3
0.8Y-0.45X=6.8
解得 X=8 Y=13
所以 王青家用水8吨 李哲家用水13吨.

6÷(3+1)=1.5元
6-1.5=4.5元

Dear Wang Qing,
I understand why you spend a lot of time watching TV. There are so many interesting TV shows and I had that problem before. I used to watch a lot of shows and couldn't even focus on doing anything else. However, I found some ways to deal with that problem. I suggest you go out with your friends. You can play ballgames with your friends. You can also go hiking, go boating or go on a picnic at the weekend. When you do a variety of activities, you will find the one you love. Then you will spend less time on watching TV. Even if you really don't like those activities, you can try to be a volunteer. I know there are lots of needs at nursing home. You can join a group and try to help the elder people there. You can sing songs for them. You can also perform short plays. Furthermore, you can find a part-time job. You can also call your friends and ask what they are going to do and simply join them. I hope this helps.
Yours,
Li Lin
我知道为什么你花那么多时间看电视.有太多好看的电视剧而且我以前也有同样的问题.我以前看很多电视剧而且甚至不能集中精力做别的事情.但是我找到了一些办法解决这个问题.我建议你多和朋友出去.你可以和你的朋友们玩球类游戏.你可以在周末徒步旅行,划船或者野餐.当你做很多活动的时候,你会找到一个你爱的活动.然后你就会少看电视.即使你不喜欢这些活动,你能尝试做志愿者,我知道很多老人院需要帮助.你可以参加一个小组然后帮助那里的老人.你能给他们唱歌.你也能表演短剧.此外,你能找一个半工.你也能打电话给你朋友问他们要做什么然后加入他们.我希望这能帮到你.
你的
李林

我们设开始先以左下点为原点,那同学坐标（8 6） 当向后转时则是以右上角的点为原点,同学坐标为（5 7）!所以这个队横（8+5）竖（6+7）!自己作图就行清楚了!

35+35乘1/8=35+4.375=39.375吨
不懂的欢迎追问,

1 Dear Wang Qing:
I'm glad to hear from you.As winter vacation is drawing near,I have made a scientific plan on how to spend it.剩下的写到你百度空间留言板去了.

解题思路：用今天读的页数减去昨天读的页数，就是今天比昨天多读的；用今天比昨天多读的页数除以昨天读的页数就是多读了百分之几．

22-16=6（页），
（22-16）÷16，
=6÷16，
=37.5%；
答：今天比昨天多读6页；今天比昨天多读37.5%．
故答案为：6，37.5．
