To be sure of getting a pair of socks of the same color, you must place yourself in the worst position.
When you take out socks without lookong (radomly), the worst scenary is that the first time you take out a sock of a color and in the second fime you take out a sock of different color. Then, the next time (the third time) you necessarily take a sock that match one of the two taken out previously, and so have a pair.
So, the answer is that you must take out three socks to be sure that you have a pair.

Answer:
- no solutions
- a finite number of solutions
- an infinite number of solutions
Step-by-step explanation:
Your question is very general, including linear and non-linear equations of any number and/or degree. In the general case you're asking about, there will be ...
- no solutions -- no values of the variables satisfy all equations
- a finite number of solutions -- all equations are satisfied for some finite set of variable values
- an infinite number of solutions -- equations are dependent (or periodic*) so the set of solutions is an infinite set
__
For 2 linear equations in 2 unknowns, there will be 0, 1, or infinite solutions.
_____
* Aperiodic equations may also have an infinite number of solutions. 1/sin(x)=0 is an example.
Answer:
1/2 or 0.5 dollars per kg of apples
The first thing to do is to find out how much a kg of apples sells for, since the question is only asking for the selling amount of a single kg. Nothing else. Each trip gets 300 dollars and delivers fifty packs. So each Pack, or P = 300/50, or P = 6 dollars
And each pack contains 12 kg of apples, so if P = 6 dollars and P = 12 kg of apples, then 6 dollars = 12 kg of apples
then 1 kg apples = 6/12, or 1/2.
So a single Kg of apples cost 0.5 dollars
62 numbers are divisible by 100 into a whole number
