put x where you need the variable to go :)  

Thats what I thought... hmmmm

I have two chances to get it right so yes :)

this is algebra 2 work lol its never that simple XD

does mit give you options for the correct answer? beacuse i believe i found it

Geometry - 10th grade

What grade level is this?

But divide that by two cuz there are two people so it would be 14?

Converse of the base angle theorem - If two angles of a triangle are congruent, then the sides opposite those angles are congruent

I think it is 28 hours, or 1 day and 4 hours.

Well, I don't know how to find the perimeter of a triangle using degrees.

Here is the hint - 

well we know that the length of KJ is 10 heres a start

No problem

Perimiter is the lengths of the sides not the angles

Thanks Rose98. Thanks snips3s. That was really nice of you guys to help me.

A triangle has 180 degrees, right. So you add 30+30=60. So, the perimeter is 180 degrees.

1b.) if you were to walk averaging 4 mph and you are only a mile from home divide 60( #of min in an hour) by 4(mph) to get 15(min of walking time)

These are the steps to solve the problem:

Verbal Model---Ask yourself what you need to know to solve the problem. Then write a verbal model that will give you what you need to know.

Labels-----Assign labels to each part of your verbal model.

Algebraic Model-Use the labels to write an algebraic model based on your verbal model.

Solve-----Solve the algebraic model and answer the original question.

Check-----Check that your answer is reasonable.

1a.) the time a train goes by is 15 min you heard one 3 min ago so subtract that to get 12 min waiting time then add the actual 8 min ride home to gert a tyotal of 20 mins to get home

1f. - it would be faster to walk home.  You heard the subway come 3mins ago so subtract that from 15 = 12 then add the 8mins it takes to ride it = 20   to walk home it would take 15mins because at 4miles per hour you and walk 1 mile in 15mins

1b. - I don't compleatly get this one but it would take 15mins to get to your house at a speed of 4 miles per hour.  this is why - 4miles/60mins = 1mile/xmins   x=15

You mean 20 minutes?

1a. - 20 minutes

Yup!!!  It was 31.88 :)  Thanks for the help!  It is 10th grade geometry
