改写这篇文章Section B,lc,ld Interviewer:Tom,I want to know about your day.Tom:OK.Interviewer:When do you get up?Tom:When do I get up?Hmm.Usually about half past five.Then I run at six o'clock.Interviewer:You run at six in the morning?Tom:Uh-huh 改写改写这篇文章, la-1/2l+lb-1/3l+lc-1/4l=0,求a+b+c的值. la-1/2l+lb-1/3l+lc-1/4l=0那么a+b-c=? la-2l+lb-3l+lc-4l=0,求式子a+b+c的值. 已知la-2l+lb-3l+lc-4l=0,求a+2b+3c的值 己知|a-2l+lb-3l+lc-4l=0,求式子a+b+c的值 英语翻译section B 的 初一英语Unit10 Section B section section 若a.b.c是整数,la-bl+lc-al=1,试求l a-b l+l b-c l+l c-a l的值.12:00以前必采 Section B和section A部分都要回答 初中数学题,说明白者事后追加30分设a、b、c为整数, 且la-bl+lc-al=1,求lc-al+la-bl+l b-cl的值. 在一定条件下可逆反应A+B=2C达到平衡后,测得c(A)=0.6mol/Lc（B）=0.1mol/Lc(C)=1.6mol/L（化学反应原理）在一定条件下可逆反应A+B=2C达到平衡后,测得c(A)=0.6mol/Lc（B）=0.1mol/Lc(C)=1.6mol/L,若ABC的起始浓度 unit2 section b 3b 英语作文 a L硫酸铝溶液中,含有b mol铝离子,则该溶液的浓度为?A.b/a mol/LB.2a/b mol/LC.b/2a mol/LD.a/2b mol/L 已知 三角形内角2Lc=LA+LB,LA-LB=40°求A B C的度数L为角符号
