Call b the amount of babysitting hours and 5 the amount of gardening hours.

10b+5g=80
b+g=12

Subtract 5 times the second equation from the first to get:

5b=20
Thus, b=4.  g=12-4, or 8.  Therefore, Sarah spends 4 hours babysitting and the rest gardening.

Based on the hints of distinguishing between <em>radical</em> and <em>non-radical</em> numbers, we have the following lists:

  1. \sqrt{3}, 2.\overline{2}, 2.5, \sqrt{5}
  2. 3.01, 3.\overline{01},3.\overline{1}, \sqrt{9}
  3. -4.\overline{1}, - 4.1, 4.01, \sqrt{17}
  4. - 2.5,  -\sqrt{5}, \sqrt{6}, 2.5

<h3>How to order numbers from least to greatest</h3>

In this question we must order sets of numbers in ascending order. A hint consists in comparing <em>non-radical</em> numbers with the <em>closest</em> <em>radical</em> numbers whose results are integers.

In consequence, we obtain the following orders:

  1. \sqrt{3}, 2.\overline{2}, 2.5, \sqrt{5}
  2. 3.01, 3.\overline{01},3.\overline{1}, \sqrt{9}
  3. -4.\overline{1}, - 4.1, 4.01, \sqrt{17}
  4. - 2.5,  -\sqrt{5}, \sqrt{6}, 2.5
