Who wants to be my Algebra tutor? :D

OpenStudy (across):

What do you need help with?

OpenStudy (anonymous):

I need help with Applications of Systems of Equations.. lol like d=rt to begin with..then some sort of equations that deal with age.. like girl 1 and girl 2 age combined is 26. Girl 1 is 2yrs older than girl 2. How old are each of the girls? (i understand this one...but theres other examples i need help on) :/

OpenStudy (anonymous):

in order to show you how to do the d=rt I need the whole problem what online school are you doing

OpenStudy (anonymous):

Im doing FLVS. and the problem is: a car and a bus leave at exactly the same time, but in opposite directions...if the bus is going 55mph and the car is going 65mph..how long will it take for the two to be exactly 180 miles apart?

OpenStudy (anonymous):

it is telling you to use d=rt

OpenStudy (across):

In that case, you can let \(f(t)=55t\) model the distance covered by the bus and \(g(t)=65t\) model the distance covered by the car. Then you're seeking to solve \(f(t)+g(t)=180\Longrightarrow t=1.5\). In other words, in one hour and thirty minutes, the vehicles will be \(180\) miles apart. There was no need for strange formulas here. :P

I need a step by step demonstration or explanation or else ^ that wont mean anything lol

OpenStudy (turingtest):

This site is not so much for tutoring from the basics, but more for helping with specific problems. Please post exact problems you are having trouble with and we will help you as best as possible. If you need help at a more remedial level I suggest you look into something like khan academy http://www.khanacademy.org/
