The puppy has greater mass: 450,000 milligrams = 450 grams, and 450<4,500
It is A and D because as you can see it is using subtraction and multiplication and I’m sorry if I am wrong I can’t see much
=743.5−462.87
=743.5+−462.87
=280.63
98.01+52.003
=150.013
74.9−16.227
=74.9+−16.227
=58.673
(1-52/2+5)=(1-26+5)=(-25+5)=-20
continuing:
-20*2*6*6= -40*6*6=-240*6=-1440
result: -1440
(1) n is not divisible by 2 --> pick two odd numbers: let's say 1 and 3 --> if , then and as zero is divisible by 24 (zero is divisible by any integer except zero itself) so remainder is 0 but if , then and 8 divided by 24 yields remainder of 8. Two different answers, hence not sufficient.
(2) n is not divisible by 3 --> pick two numbers which are not divisible by 3: let's say 1 and 2 --> if , then , so remainder is 0 but if , then and 3 divided by 24 yields remainder of 3. Two different answers, hence not sufficient.
(1)+(2) Let's check for several numbers which are not divisible by 2 or 3:
--> --> remainder 0;
--> --> remainder 0;
--> --> remainder 0;
--> --> remainder 0.
Well it seems that all appropriate numbers will give remainder of 0.
