Dan wants to determine the number of liters of a 20% acid cleaning solution that he should combine with an 80% acid cleaning solution to create 50 liters of a 60% acid cleaning solution.
Part A
Let z represent the number of liters of the 20% acid cleaning solution. Which equation represents this situation?
0.6(50) 0.22 +0.83
0.25 +0.8(2 +50) -0.6(50)
© 0.22 +0.8(50 - 2) = 0.6(50)
0 0.6(50) -0.22 +0.8(x - 50)
(b)
Part B
How many liters of the 20% acid cleaning solution should Dan use? Round your answer to the nearest tenth of a liter.
liters of the 20% acid cleaning solution
Dan should use

step-by-step explanation:

hi do you need an answer for your question?

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

c and d is your answers.
