(2) y = 12z, where z is an integer --> y=12zy=12z --> x=8∗12z+12x=8∗12z+12 --> x=12(8z+1)x=12(8z+1). So, we have y=12zy=12z and x=12(8z+1)x=12(8z+1). Now, as zz and 8z+18z+1 do not share any common factor but 1 (8z and 8z+1 are consecutive integers and consecutive integers do not share any common factor 1. As 8z has all factors of z then z and 8z+1 also do not share any common factor but 1). Thus, 12 must be GCD of xx and yy. Sufficient.

Now, about your question: we don't know which is the source integer in the set, if it's -1 than odd number less than it won't be in the set but if source integer is let's say -11 than -3 will be in the set. So -3 may or may not be in the set.
时速为60所用的总时间= 50时速用的时间 + x时速用的时间
结论:irradiation造成的损失小于 cooking造成的损失
(2) ce=5, ca=5, so ad= ca+cd=6, so ab=3
A,的却存在经济萧条的时间节点限制,但是。。。好难想到
居然做对了....有种赌一把赌对了的感觉。还是再仔细看看题。
果:销量没变,但装配工人减少。
