A group of 108 people attend a ball game. There were five times as many children as adults in the group. Write a system of equations that could use to set up this problem, where a is the number of adults and c is the number of children in the group.

I need help making the equations!!!!

UK Patent GB 2313657B Generating superheated steam using microwaves and water. This can store vast amounts of surplus electrical energy from power stations. I want to make it free to all and anyone who can develop the process. Any useful engineering or accademic links to promulgate the patent is welcome. I give it freely to help mitigate our global energy problem.

I forgot how to find velocities of things. I know it's displacement/time but for example if someone drives 1920 miles in 32 hours and then goes back the same way in the same time his average speed both ways would be 1920/32 of course. His displacement would be 0 though, so would his velocity be 0?

Hey, we have a project in my chemistry class. we have to dress up like a certain element, but be very creative. Most of the class has chosen their outfit, taking the very easy and most popular ones.
I was thinking about titanium and dressing up like a football player, as in the Titans. I dont know though.
Any other ideas on what I can be? thanks!!
