Best ResponseYou've already chosen the best response.0Hi jmallis, so can I assume that this is a right triangle?

Best ResponseYou've already chosen the best response.0Got it, so, do you know how to set up your equation? We know the perimeter is 370 meters, so how do you think we'd set that up?

Best ResponseYou've already chosen the best response.0Great job! So, now you can get rid of the parentheses (it's not relevant in addition) and add your factors.

Best ResponseYou've already chosen the best response.0\[5x + x + 6x 2 = 12x 2 = 370\]

Best ResponseYou've already chosen the best response.0Does that make sense? So now you just have an equation with: \[12x  2 = 370\]

Best ResponseYou've already chosen the best response.0Great, so do you know how to solve that equation you have left?

Best ResponseYou've already chosen the best response.0Ok, do you have much experience with algebra?

Best ResponseYou've already chosen the best response.0Exactly! You add 2 to 370. So now you have: \[12x = 372\]

Best ResponseYou've already chosen the best response.0Brilliant, way to go  so 372 / 12 = 31. Which is your X

Best ResponseYou've already chosen the best response.0So now what you need to do is put that x back into your three lengths from the original triangle, put em in order, and voila  you've got your answer

Best ResponseYou've already chosen the best response.0Correct  you can put what you get here if you want so I can make sure I'm getting the same thing

Best ResponseYou've already chosen the best response.0Well, let's go through them. You have 3 separate lenghts: x, 5x, and 6x2. So, replace X with 31 for all of these

Best ResponseYou've already chosen the best response.0Can you help me with another problem I only have like 9 minutes battery life on my laptop. Lakeview is 85 miles from Springfield. Irania must go to the law library in Springfield to get a document for the law form for which she works. Find how long it takes her to drive round trip if she averages 54 mph. Takes approximately __ hours and __minutes

Best ResponseYou've already chosen the best response.0Ok, so  54 mph. So, take the total mileage (85 miles) and divide that by 54 mph. That gives you the approximate time to get there. REMEMBER though that this is oneway, you need to multiply your answer by 2 to get the round trip. Hopefully you get this in time...

Best ResponseYou've already chosen the best response.0so whats hours and minutes? and thankyou again

Best ResponseYou've already chosen the best response.0hey, so the key is that when you divide, you'll come up with a decimal. You need to multiply that decimal by 60  in order to give you the mins
