您好! 第六题:解:设乙车的速度为xkm/h,则甲车的速度为(2x+20)km/h. 1/2x+1/2(2x+20)=298. x=192 2x+20=2乘192+20=404 第十题: 分析:第一次相距36km时,两人是相对而行,还未曾相遇过;第二次相距36km时,两人是相背而行,已经相遇过了。
解法一:解:从10时到12时王力,陈平两人共行驶36+36=72(km),用时2h,所以从8时到10时王力,陈平用时2h也行驶72km,设A,B两地间的路程为xkm,则x-72=36,得x=108. 解法二:解:设两地间的路程为xkm,上午10时,两人走的路程为(x-36)km。速度和为x-36/2 km/h,中午12时,两人走的路程为(x+36)km,速度和为x+36/4 km/h,根据速度和相等列方程,得x-36/2=x+36/4,得x=108。好啦!希望能帮到你!o(∩_∩)o..4. 七年级上册数学应用题用写答吗?
七年级上册数学应用题用写答入学区别于其他学科的。一个主要特征就是在解题时的特殊格式。要有理有据有因有果有解有答的,去完成各类问题的求解,他的文科平铺直叙似的用文字堆砌的。问题是不一样的。数学是一个抽象。讲理的学科。因此说明某个问题时都要有理有据并且最后还要扣题答出结果。

3. 七年级上册人教版数学书99页?
您好! 第六题:解:设乙车的速度为xkm/h,则甲车的速度为(2x+20)km/h. 1/2x+1/2(2x+20)=298. x=192 2x+20=2乘192+20=404 第十题: 分析:第一次相距36km时,两人是相对而行,还未曾相遇过;第二次相距36km时,两人是相背而行,已经相遇过了。
解法一:解:从10时到12时王力,陈平两人共行驶36+36=72(km),用时2h,所以从8时到10时王力,陈平用时2h也行驶72km,设A,B两地间的路程为xkm,则x-72=36,得x=108. 解法二:解:设两地间的路程为xkm,上午10时,两人走的路程为(x-36)km。速度和为x-36/2 km/h,中午12时,两人走的路程为(x+36)km,速度和为x+36/4 km/h,根据速度和相等列方程,得x-36/2=x+36/4,得x=108。好啦!希望能帮到你!o(∩_∩)o..4. 七年级上册数学应用题用写答吗?
七年级上册数学应用题用写答入学区别于其他学科的。一个主要特征就是在解题时的特殊格式。要有理有据有因有果有解有答的,去完成各类问题的求解,他的文科平铺直叙似的用文字堆砌的。问题是不一样的。数学是一个抽象。讲理的学科。因此说明某个问题时都要有理有据并且最后还要扣题答出结果。本站涵盖的内容、图片、视频等数据系网络收集,部分未能与原作者取得联系。若涉及版权问题,请联系我们删除!联系邮箱:ynstorm@foxmail.com 谢谢支持!
