什么笑得什么造句

列式计算：-6x(-0.25)x十四分之十一?-9X-（11）除3除（-3） -6x(-0.25)x11/14 计算 X+25=6X-75怎么算 (6x-1)²-25=0 怎么算 为什么闰年要除以400谢谢了,为什么算闰年的时候尾数是00的要除以400啊?不可以除以4么? 在一个除法算式里,被除数(不为零)除数与商这三个数的积除以被除数,得数是（ ） Tom ________ (play) soccer tomorrow . Tom can play __ soccer and Mike can play __ drums? He watched the children_soccer yesterday afternoon A to play B played C play D playing说明详细原因 x-3=4(x-3)² ,Tom? Yes,I play soccer every day ?,Tom?Yes,I play soccer every day ?Yes,I'm in a soccer club.You look very healthy. ?I like to eat eggs and hamburgers for breakfast.Do you like fruit Tom plays soccer every day,___ ____ soccer every day?第一个空填who还是whom But he don't play soccer.His s[],Tom,likes soccer ball. x²-x-4/3=0是用配方法 They played soccer (in the park yesterday afternoon) 对打括号部分提问—— —— —— —— they play soccer?(填空) 设函数f（x）=向量m乘向量n,其中向量m=（2cosx,1）,向量n(cosx,√3sin2x).三角形ABC中,f（A）=2,b=1,三角形面积为根号3/2,求a+b+c/sinA+sinB+sinC they played soccer yesterday afternoon改为一般疑问句并作肯定回答. 若分式x2-4/x-2的值为0,则x的值为 (写下过程) 是let the boy play soccer还是let the boy plays soccer look!The boy ＿＿＿（play） soccer in the flook!The boy ＿＿＿（play） soccer in the field must be Ann ｀ If it was half past four an hour ago,it is_____now.帮下, 六点半英语怎么说?我翻译出来是half past hour ,翻译回去是六年半.超奇怪 Let's------there at half past hour .A;goes B;go C;to go D;going (a+2)(a-2)(a²*²+4a²+16) 下列计算正确的是A{√2-2√2=-√2}B√8a²=4a(a＞0)C{√（-4×(-9}=√-4×√-9D{√6÷√3=√3} (a²一4a)²十8(a²一4a)十16 KID 与CHILD有什么不同处 kid和child的区别在哪里 除数是32,商是8,被除数有可能是那些数字 两个数相除的商是1.6,如果被除数、除数和商相加得32.8,那么除数和被除数各是多少?能不用方程尽量不用~算式最好.如果各位高人时间够的话希望能帮我解释下, 被除数、除数、商三个数的和是71,商是8,被除数比除数大几? one and a half hour 中hour是否加s
