甲级茶叶2千克和乙级茶叶6千克的价钱相等,买1千克甲级茶叶和2千克的乙级茶叶共付款145元,求甲乙两种茶叶的单价?为什么是29×3=87,29×7是哪里来的,29×3=87,可不可以这样理解,29是乙级茶叶的单

为什么是29×3=87?
我的回答是:乙的单价是29元,甲的单价是乙的单价的3倍(由甲级茶叶2千克和乙级茶叶6千克的价钱相等)可以看出,那么甲的单价=29×3=87元
可不可以这样理解,29是乙级茶叶的单价,那么把千克甲茶当3千克乙茶看,实际上就是是3千克甲茶,是不是这样啊 为什么?
不对.29只能表示1/3千克甲茶,可以把一千克甲当做3千克乙查看,但是87千克才是3千克乙茶.
懂了吗?
145/(2+3)=29(元/千克)
29*3=87(元/千克)
(PS:一千克甲茶叶=三千克乙茶叶,那么1KG甲茶叶和2KG乙茶叶就=(2+3)KG乙茶叶,那么乙茶叶就是(145/5)元/KG了,甲茶叶就=乙茶叶的价格*3)

ing; but any doubts you might have would certainly have been swept away if you'd been there to see what happened next. Mameha asked my sister's sign and looked up the same information about her. "Well," she said after looking at it for a while,Breitling Watches, "it reads, 'An auspicious day for small changes.' Perhaps not the best day for something as ambitious as running away, but certainly better than the other days that week or the next." And then came the surprising thing. "It goes on to say,Ralph Luaren Outlet, 'A good day for travel in the direction of the Sheep,'" Mameha read. And when she brought out a map and found Yoroido, it lay to the north northeast of Kyoto,Maglioncini Ralph Lauren, which was indeed the direction corresponding to the zodiac sign of the Sheep. Satsu had checked her almanac. That was probably what she'd done when she left me there in the room under the stairwell at the Tatsuyo for a few minutes. And she'd certainly been right to do it; she had escaped, while I hadn't.This was the moment when I began to understand how unaware I'd been-not only in planning to run away, but in everything. I'd never understood how closely things are connected to one another. And it isn't just the zodiac I'm talking about. We human beings are only a part of something very much larger. When we walk along, we may crush a beetle or simply cause a change in the air so that a fly ends up where it might never have gone otherwise. And if we think of the same example but with ourselves in the role of the insect,Moncler Femme, and the larger universe i

单纯的价格:甲87乙29,计算的话是个二元一次方程,但是一千克甲茶在数学上是等于3千克乙茶,但是生活中不一样,喜欢喝好一点茶的,一千克甲茶换5千克乙等茶,也是不换的,在他概念里只有甲等茶和乙等茶。
