The answer is B) 4 : 16

Explanation:
RATIO FOR 1 MOLECULE OF ACETIC ACID:
2 carbon atoms : 2 oxygen atoms : 4 hydrogen atoms
Since its asking how many for 2 MOLECULES, we double the ATOMS (we multiply all by 2)
RATIO FOR 2 MOLECULES OF ACETIC ACID:
4 carbon atoms : 4 oxygen atoms : 8 hydrogen atoms
The question only asks for the ratio of carbon atoms to ALL atoms. To calculate all atoms, we add 4 + 4 + 8 = 16
So if there are 4 carbon atoms and the sum of all atoms is 16, out final ratio answer is:
B.) 4 : 16

uysha [10]

Answer:

22-6x>4  

One solution was found :

                  x < 3

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :  

                    22-6*x-(4)>0

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  18 - 6x  =   -6 • (x - 3)  

Equation at the end of step  1  :

Step  2  :

2.1    Divide both sides by  -6  

Remember to flip the inequality sign:  

Solve Basic Inequality :

2.2      Add  3  to both sides

            x < 3

Inequality Plot :

2.3      Inequality plot for

        -6.000 X  + 18.000  <  0

 x < 3
