Question

Помогите пожалуйста решить!!!!!!!!!

Answer 1

$|y - 4 \frac{1}{2} | + 3 |x + \frac{1}{2} | = \\ = |3 - \frac{9}{2} | + 3 | - 5 \frac{1}{2} + \frac{1}{2} | = \\ = | \frac{6}{2} - \frac{9}{2} | + 3 | - \frac{11}{2} + \frac{1}{2} | = \\ = | - \frac{3}{2} | + 3 | - 5| = \\ = \frac{3}{2} + 3 \times 5 = \frac{3}{2} + \frac{15}{1} = \frac{3}{2} + \frac{30}{2} = \\ = \frac{33}{2} = 16.5$
