Odpowiedź:

$\dfrac{-30\cdot(-0,5)^2+(-30)}{-0,1\cdot[-29,4+9\cdot(-0,9)]}=\dfrac{-30\cdot0,25-30}{-0,1\cdot(-29,4-8,1)}=\dfrac{-7,5-30}{-0,1\cdot(-37,5)}=\\\\\\=\dfrac{-37,5}{3,75}=-10$

$lub\\\\\dfrac{-30\cdot(-0,5)^2+(-30)}{-0,1\cdot[-29,4+9\cdot(-0,9)]}=\dfrac{-30\cdot(-\frac{1}{2})^2-30}{-\frac{1}{10}\cdot(-29,4-8,1)}=\dfrac{-\not30^1^5\cdot\frac{1}{\not4_{2}}-30}{-\frac{1}{10}\cdot(-37,5)}=\\\\\\=\dfrac{-\frac{15}{2}-30}{\frac{1}{10}\cdot\frac{375}{10}}=\dfrac{-\frac{15}{2}-\frac{60}{2}}{\frac{1}{\not10_{2} }\cdot\frac{\not75^1^5}{2}}=\dfrac{-\frac{75}{2}}{\frac{15}{4}}=-\frac{75}{2}:\frac{15}{4}=-\frac{\not75^5}{\not2_{1}}\cdot\frac{\not4^2}{\not15_{1}}=-5\cdot2=-10$

Odpowiedź:

Szczegółowe wyjaśnienie:

-30*(-0,5)^2+(-30) 30*0,25+(-30) 7,5+(-30) -12,5

---------------------------- = ------------------------ = ---------------- = ---------- =

-0,1*[-29,4+9*(-0,9)] -0,1*[-29,4+-8,1] -0,1*37,5 -3,75

-12,5:0,25 50 50:5 10 1

= ----------------- = ------ = -------- = -------- = 3 -------

-3,75:0,25 15 15:5 3 3
