If 7y + 9 represents an odd integer, which of the following represents the next smaller odd integer?
选项
A、7(y+l)
B、7(y-2)
C、7(y+3)
D、7(y+2)
E、7(y-2)+ l
答案
A
解析
The correct answer is A. To answer this question, note that odd numbers are every other number: 1, 3, 5, 7, ... , etc. So an odd number plus or minus 2 would create another odd number. Therefore, 7y+7 would be the next smaller odd integer. Factor out a 7 to get 7(y + 1).
