问答题If x is an integer, is (18+54)/x an integer? (1) 18＜x＜54 (2) x is a multiple of 18
问答题
If x is an integer, is (18+54)/x an integer? (1) 18＜x＜54 (2) x is a multiple of 18
参考解析
解析：
若18＜x＜54，当x=36时，该式为整数，当x=37时，该式不为整数；条件2也不能确定该式的值；将两条件相结合，可知x=36，原式为整数，故本题选C项。
若18＜x＜54，当x=36时，该式为整数，当x=37时，该式不为整数；条件2也不能确定该式的值；将两条件相结合，可知x=36，原式为整数，故本题选C项。
