1990 - 11 & 12

This new set is from the 1990 test.
Difficulty: Easy. My algebra II kids did this one without algebra and then realized how much easier it is with systems.

Difficulty: Easy.

Standard instructions for this series: No calculator allowed. Express answers in reduced form. Rationalize denominators. Radicals must be reduced. All numbers are base ten unless otherwise specified. Do not approximate radicals or π. Leave such answers as 1025π or √39, for example. Source: UVM Math Contest 2013

answer 11, answer 12, Published 5/11.

    The second one has two solutions. Makes it, imho, "almost easy" but not quite.

    In more recent tests, they make sure to specify that there are two answers or they ask for the sum of the two. I think that this test is from the time before the current coordinator.
