Answer : 1. "TRUE"
Explanation :

Answer: A) TRUE Explanation: True, Water is a Pure substance and not a mixture.   We know that, A mixture is when two or more substances combine physically together. You can find that the mixture retains the properties of the original components. In water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.   Therefore, water is not a mixture; it is a compound and it is pure.

Answer :
Explanation :

We can make an equation: 3(100000 + x) = 10x+1 (Why? Well, adding 100000 puts a 1 at the front of a five-digit number, and multiplying by 10 and adding 1 puts a 1 at the end of a number) Solving this gives: 10x+1 = 3(100000 + x) 10x+1 = 300000 + 3x 10x = 299999 + 3x7x = 299999x = 299999/7 = 42857 The answer is 42857 (142857 is three times smaller than 428571).
