If x and y are points on the number line, what is the value of x + y ?
(1) 6 is halfway between x and y.
(2) y = 2x
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
是halfway不是midpoint。。。
有什么区别。。。
一条way,我把它half了一下,和一条直线,我找到他的midpoint,有什么区别? 你真是猪脑子
请问你知道教养两个字怎么写吗?
对不起,和你道歉。
我也觉得在数轴上好像没什么区别...
