Question

Помогите срочно по матиматике!!!

Answer 1

$3x - 2 |y - 1| = - 3 - 2 | - 4 - 1| = - 3 - 2 | - 5| = - 3 - 2 \times 5 = - 3 - 10 = - 13 \\ | - 4| + |1 - 3x| = 4 + |1 - 3 \times 2.4| = 4 + | - 7.2| = 4 + 7.2 = 11.2$

$5 |5.2 + 2y| + 2 |x| = 5 |5.2 + 2 \times ( - 4)| + 2 | - 1| = 5 |5.2 - 8| + 2 = 5 | - 2.8| + 2 = 5 \times 2.8 + 2 = 14 + 2 = 16 \\ 2 |2x - \frac{3}{8} | + \frac{3}{4} =2 |2 \times \frac{3}{2} - \frac{3}{8} | + \frac{3}{4} = 2 |1 - \frac{3}{8} | + \frac{3}{4} = 2 | \frac{5}{8} | + \frac{3}{4} = 2 \times \frac{5}{8} + \frac{3}{4} = \frac{5}{4} + \frac{3}{4} = \frac{8}{4} = 2$

$(4 \frac{3}{4} - 2) \div \frac{33}{2} + 1\frac{6}{11} \div \frac{17}{8} = \\ 4 \frac{3}{4} - 2 = 2 \frac{3}{4} \\ 2 \frac{3}{4} \div \frac{33}{2} = \frac{11}{4} \div \frac{33}{2} = \frac{11 \times 2}{4 \times 33} = \frac{1 \times 1}{2 \times 3} = \frac{1}{6} \\ 1 \frac{6}{11} \div \frac{17}{8} = \frac{17}{11} \div \frac{17}{8} = \frac{17 \times 8}{11 \times 17} = \frac{8}{11} \\ \frac{1}{6} + \frac{8}{11} = \frac{11}{66} + \frac{48}{66} = \frac{59}{66}$
