Question

Помогите с математикой!!!!!!!!!!!!!

Answer 1

$|23|=23 \ |-3|=3 \ |0|=0 \ |2.5|=2.5 \ |-3 frac{2}{3} |=3 frac{2}{3} \ |-2|=2$

Если $|x|=3 frac{1}{3}$ и $x<0$, то $x=-3 frac{1}{3}$

$|-4.1|:|-41|=4.1:41=0.1$

$|2.5|cdot|-4|-| 2frac{1}{3} |cdot|- frac{3}{4} |=2.5cdot4- frac{7}{3} cdot frac{3}{4}=10-1.75=8.25$

$|-18 frac{1}{3} |=18 frac{1}{3} \ |41 frac{1}{3} |=41 frac{1}{3} \ n=41-18=23$

$|2x-1|=4 \ 2x=-1=pm4 \ 2x=1pm4 \ x= frac{1pm4}{2} \ x_1=2.5 \ x_2=-1.5$
