A.season
B.animal
C.fruit
D.weather
答
D
题目的意思是:你把YSNOW这五个字母重新排列组合,得到的单词是关于那个方面的?
重新组合后的单词是snowy,下雪的(天气).这是关于天气的,所以选D.Some hens and rabbits live in one big house.Yhey have 20 have and 54 legs altogether.How many hens are there?谢谢,能再帮我回答下?这是基本的鸡兔同笼问题。20个头、54条腿,问有几鸡几兔。基本的二次方程联立求x + y = 202x + 4y = 54解得x = 13,y = 7。有13鸡7兔。几只母鸡?我不是已经回答了吗?最后一行看不懂?
