C A chemist 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?

Need solving this second acceleration problem.

Marking brainliest for original answer.. are these two triangles similar? how can you tell?
