    well, it says that point S is between R and T so RT = RS + ST

    60 = 3x - 16 + 4x - 8 the first step is to solve for x, do you think you can take it from here?

    yup, that's the first step. now that we know what x is, we can now find RS and ST RS = 3x - 16 = ? ST = 4x - 8 = ?

    ah, sorry, got distracted there for a sec let's draw the diagram and label it based on what the problem tells us |dw:1440113699458:dw|

    now the problem tells us that AC and CD are equal, so what do you think each of them are?|dw:1440113761200:dw|

    now, it wants us to find the length of every segment in the diagram, so I'll make a list here: AB = 3 BC = 3 CD = 6 AC = 6 CD = 6 BD = 9 AD = 12 so, how many are greater than 3?

    5

    so our probability is 5/7

    (since there are 7 total segments) and that ends up being our final answer for #31

    well, the abdomen is easy enough, it's 2 and 1/4 of an inch, just reading off the ruler

    for the thorax, the right end is at the 4-inch mark, approximately, and the left end is at 2 1/4 inches so (4) - (2 and 1/4) = 1 and 3/4 inch for the thorax

    so (4) - (2 and 1/4) = 1 and 3/4 inch for the thorax

    well, we can measure the abdomen by looking at the ruler, since the abdomen starts at 0 for the thorax, though, it doesn't start at 0 so we need to find both ends and subtract
