陈丽和哥哥两人乘一辆出租车从A地到B地,行驶到两地中点时,小明上车,三人合乘到B地,司机收10元……

1.(1)假如陈丽11题都对,则得分为：11×10=110（分）
现在只得了78分,少了110-78=32（分）,因为从一题对的变为错的要少10+6=16（分）
所以,错的有32÷16=2（题）,答对的有11-2=9（题）
（2）解法和上面一样,算式为
14×10-40=100（分） 100÷16=6.25（题）
（我估计你这个小题的数字抄错了）
2.32+25-45=12（人）
3.我认为要使花的时间少就是让最快好的人早点走,其他要打水多的后面打水.这样,热水瓶少的人打完就走,就不用等了.所以我计算的总共时间为：
1+（1+2）+（1+2+3）=10(分钟）
答：先王阿姨,再张阿姨,再李阿姨.共需要10分钟.
4.52÷2=26（棵） 一边载的树的棵树
26-1=25（个） 共有的间隔数
75÷25=3（米）
答：相邻两棵树之间的距离是3米.
5.“比赛后发现预测的说法各对了一半”,说明第一个人说的,和第二个人说的都有一半对了,既甲要么是第二,要么是第一；丁要么是第三,要么是第二.
第三个人说：“丙第二名 丁第四名”,丁不可能时第四,所以丙是第二.
丙是第二,甲就不可能使第二,所以,甲是第一.
甲是第一,说明第一个人说甲是第二是不对的,丁是第三是对的.所以丁是第三.
剩下还有个乙,它就是第四.
总结：甲第一,丙第二,丁第三,乙第四.

可以,比值可以用分数、小数、整数来表示.

You:Hey Li,how's it going?
Li:I am good,thanks,you?
You:Very well,thanks.Li,this is my friend Jin,he is in my class.Jin,this is my friend Li,she lives next door to me.

I am Chen Li.Today,I wrote to you is to tell one thing.Taiwan on September 29 you to the next 103 orders The goods have been received.However,we found a box of goods is not determined by our goods.Most of this cargo Christmas ceremony goods and toys,I hope that you will investigate this matter as soon as possible.and as soon as possible to replace the wrong goods.I hope you will soon return.This is the wrong boxes of goods inventories.Please tell us the how to dispose of boxes of goods.

设直线与Y轴交点为B,
由题意,可知
½×OA×OB=9
即：½×6×OB＝9
OB＝3
∴点B的坐标是（0,3）或（0,-3）
当点B为（0,3）时,设一次函数的解析式是y=kx+b,将A（6,0）、B（0,3）代入,得
{6k+b=0
b=3
解得：{k=-½
b=3
∴一次函数的解析式是y=-½x＋3;
当点B为（0,-3）时,可求得一次函数的解析式是y=½x－3；

∴一次函数的解析式是y=-½x＋3或y=½x－3.
