The answer to this question is (6,-1)
Answer:
The correct option is B. two oxygen atoms
Step-by-step explanation:
The molecular formula for carbon dioxide is given by :

Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.
And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.
So, The prefix of the first word that is C is 1
⇒ One molecule of carbon dioxide contains one atom of Carbon.
The prefix of the second word that is O is 2
⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.
Therefore, The correct option is B. two oxygen atoms
Step 2 I think because you would take 3-4 and not just put x
we are given to find

we know that

where
i is number of rows
j is number of column
Here , we get
i=2
and j=3
so,
means second row and third column
we can look at matrix and find element
we can see that
that element is -21
so,
...........Answer
Answer:
4 > x/2.1
Step-by-step explanation:
4 cannot be less than anything, so the inequality sign has to be "eating" the 4.
4 > ?
The quotient of a number x and 2.1 is simply saying division
4 > x/2.1
