A chemist mixes 4 liters of one acid solution with 10 liters of a 40% solution, resulting in a 30% acid solution. The table shows the amount of each solution used. A table titled Acidity, with Liters, Acid Concentration, ad Total. The first row is x percent acid, with 4, x, and blank. The second row shows 40 percent Acid, with 10, 0.40, and 4. The third row shows Mixture, with 14, 0.30, and blank. What is the value of x, the acid concentration of the first solution? 0.05 0.10 0.15 0.20

0.05

Step-by-step explanation:

                             Liters    Acid Concentration   Total

x percent acid      4            x                                  -  

40 percent Acid  10           0.40                            4

Mixture                 14           0.30                            -

The total of the mixture is:

14*0.3 = 4.2

This total is the addition between the total of x percent acid and the total of 40 percent acid. Therefore:

total of x percent acid  = 4.2 - 4 = 0.2

This total is computed as

total = liters*acid concentration

Therefore:

x = total/liters = 0.2/4 = 0.05

which means that the solution was 5 percent acid

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

it has changed from the width and the height.
