2/3 of 60 minutes = 40 Minutes for Kaitlin
Judy spends 1 1/2 times of Kaitlin = 60 Minutes
Explain why Judy's homework time is between 2/3 of an hour and 1/2 hour? I have no idea what is meant by that?
so, Judy's time is really 1 hour exactly.
and on the number line, we could place that 1 in between the first half and the two thirds of the of the next number, as you see above.
the answer is (4,3)
since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
