Best ResponseYou've already chosen the best response.2Let's just draw number line:dw:1436910305137:dw Since they didn't say about about the value of R, S, and T, we can just assume that R = 0. So S would be 6, and T would be 15.

Best ResponseYou've already chosen the best response.2"midpoints" is basically point that lie exactly in middle. So midpoint of RS is 3, because R is 0 and S is 6 \(\dfrac{0+6}2=3\) Another way to see is that distance between R and S is 6, so half of that is 3.

Best ResponseYou've already chosen the best response.0Hopefully you found the answer to part A dw:1436912651346:dw the distance between the midpoints is the distance from A to B 3+4.5 = 7.5
