建筑工地用5辆大车和4辆小车一次运来沙石42.5吨

Question

建筑工地用5辆大车和4辆小车一次运来沙石42.5吨，每辆大车比每辆小车多运4吨，每辆大车和每辆小车各运沙石多少吨？？
能不能写出算式……
各位啊，他们明明说每辆大车比每辆小车多运4吨，你们的答案都不对啊……

Answer 1

5辆大车多运4吨，就是5*4=20 42.5-20=22.5 22.5除9=2.5 所以九辆车如果都是小车的话就是每辆2.5吨咯，然后那5辆大车再分别加4吨就是7.5 所以小车2.5 大车7.5 我刚才算错了，这个是对的，杀了我很多脑细胞啊

Answer 2

5(x+4)+5x=42.5 「设的是小车的吨数」算出来是，小车：2.25 大车：7.25

Answer 3

4.5
2.5
