Sometimes it helps to right seperate equations for each person's age. a + 5 = Tisha 2a + 3 = Alex 2tisha = Sara I guess you could have that system of equations be your answer, just pick a variable for each person's name. I'm not exactly sure how you would combine ...

**Read this first! I found the formula for circumference.**

The circumference formula is: c = pi times diameter OR c = 2piradius Sorry, I don't know how to make a pi symbol on the keyboard. :) I couldn't find the area formula... but just place 9.3 in where I said radius. Hope I helped! :)
*February 23, 2009*

**math**

I don't remember the equations exactly, but I know there are equations to find that. Just go an a search engine and type in "circumference equation" or "area equation" and you'll find it.

Like I said with awl, I found the circumference forumla, which is: c = pi times diameter OR c = 2 times pi times radius I can't find the area formula. :( Just place in 3 where I said "radius." Hope I helped! :)

Oh, I kind of skimmed what you said and didn't notice the x-y=2... I'm sorry! Thanks so much though! :) P.S: Is the correct answer 375 miles away from the station, meaning x=5 and y=3?

**Question**

You see, here's what I did. I changed the "t" in the equation that both of you gave me (75t=125(t-2)) to an x so I could use elimination to solve the problem. That made that equation be 125x - 250 = 75x + 75x = 125 y That's where my problem comes along... it ...

Well, "which I thought had lost" at the end of the sentence should be "which I thought I had lost." Unless that was a typo, I don't see any other things that need to be corrected.
