这道英语的数学题(52题)求过程和答案,拜托啦!
1. 将□理解成x
没注意括号,式子变成4800÷75+12x=208
所以 12x=208-4800÷75
12x=208-64
x=12
正确的式子应该是 (4800÷75+12)×12=912
2. 设乙车每次运x箱,则甲车每次运(x+4)箱
8x-5(x+4)=13
8x-5x-20=13
3x=33
x=11
所以乙车每次运11箱
3. 设买了x瓶消毒液,(56-x)瓶洗手液
5x+3(56-x)=216
5x+168-3x=216
2x=216-168
x=24
56-x=56-24=32
3×24+5*32=232
232-216=16
所以药店受损失,学校应到药店多付16元

乜祥金刚: 必须从28下手,因为这个数字比较小,它的约数也最少,那么a与c可能是4、7或2、14(1和28这组的可能性不大,先排除),这四个数中只有7可以被525除尽,所以a是7.那么可以推断出b是75,c是4.
