solve y 6.3=0.9y thats all the question i dont understand it so thats why im trying to get the answer to the problem
1 answer:
What it wants you to do is to put it into a form where on the one side of the equation there is y and nothing else. for this, we need to get rid of the 0.9.
how do we do that?
we divide both sides of the equation by 0.9:
6.3/0.9=y
that's ugly, right? but if both denominator and nominator are decimal fractions of the same sort; we can multiply both by 10 and get rid of the point:
63/09=y
and...
so basically 7=y, or y=7
and this is the solution!

Consider the Set A = {X | X is an even whole number between 0 and 2 } = .
Since, whole numbers are the set of numbers starting from zero upto infinity.
Even numbers are the numbers which are exactly divisible by '2'.
So, we have to find the even whole number between 0 and 2.
Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.
Therefore, there is no even whole number between 0 and 2.
So, this set is empty.
Therefore, A = { X | X is an even whole number between 0 and 2} =
