Question

Помогите срочно по матиматике!!!

Answer 1

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

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

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