Let the 2 equal lengths be represented by 2p. Then you can write the equation of ratios
p 2p
---- = -------
16 x+4
which simplifies to
1 2
----- = ------
16 x+4
then x+4 = 32, and x = 28 (answer)
Remark
Many calculators have a key that will do this in one step. Mine is one of them. So let's start with the answer and then we'll do it the long way.
9C3 = 84. You put it into your calculator as 9 2nF nCr 3 =
Solution

3*4*7 = 84 which is what you set out to show.
14) The answer is a) y = 2x. 2 is the slope and the line does not cross over the Y axis in this picture so there is not a Y-intercept you can see.
15) You pretty much just estimate. On the graph when you find 50 minutes and go up its around 140. 50 x 2 is 100 minutes. so just multiply 140 by 2 and its 280 so just round to the closest one.
20% because 75 is the total price and 75 over 15 is 5 and 100 divided by 5 is 20
