【題目】The letter “X” often represents an ________ (know) number in some Math exercises.

【答案】unknown

【解析】

句意：在一些數(shù)學(xué)練習(xí)中，字母“X”通常表示一個(gè)未知的數(shù)字。

根據(jù)“The letter “X” often represents”可知，這里是說(shuō)字母“X”表示一個(gè)未知數(shù)字。這里是形容詞作定語(yǔ)，所給單詞know，動(dòng)詞，知道，這里用形容詞unknown，不知道的，未知的。故答案為unknown。
