Before the universe existed there was nothingness, no space, no time, no matter to be formed or expanded?

How can something form from complete nothingness? How can time and space be formed from nothing?



all this is created from a higher creator? maybe there was no before the universe, it was always here with no beginning? Maybe none of this is real?

What do you think?

I have two open ended questions I don't understand on my math homework. We have 20 questions in all so obviously there are some we won't understand. The questions are below.

16. A quantity of 22% acid solution is being diluted with some 8% acid solution. The final solution must be 12% acid and contain 101 mL. How much of each solution must be added to accomplish this?

A. Write a system of equations that describes this situation.
B. Solve the system.

19. PhotoLab charges $9.00 for processing a 24-exposure roll of film and $12.00 for processing a 36-exposure roll. After their class trip, Mr. Renkens' 8th grade class sent 22 rolls of film to be developed and paid $219 for processing.

A. Write a system of equations that describes this situation.
B. Find the number of rolls of 24-exposure and the number of rolls of 36-exposure film that were procesed.

All help in solving these open-ended questions is appreciated.
