Achemist has a container of 12% peroxide solution and a container of 20% peroxide solution. she needs to mix the two solutions to create 100 ml of a 14% solution. if x represents the amount of 12% peroxide solution and y represents the amount of 20% peroxide solution she needs, which matrix equation can determine the amount of each solution she needs to make the 14% solution?

Step-by-step explanation:

We are given that,

The amount of 12% peroxide solution = x and the amount of 20% peroxide solution = y.

Since, the total amount of the solution to be made is 100 ml. So, the equation is

Also, the sum of the 12% solution and 20% of the solution is resulting in 14% solution. Then, the equation is

answer: a.   one is a factor of every whole number since every number is divisible by itself.
