Oblicz:
a) a) \sqrt{1}\frac{9}{16}*(-2)^{2}+1,2*\frac{5}{12}=

b) 2\frac{1}{2}-\frac{1}{2}*\sqrt[3]{3}\frac{3}{8}+2^{-2}=

c) (\frac{3}{4})^{-1}-(-1\frac{1}{3})^{2}:0,9=

d) 0,8* \frac{3}{2^{3}}-\frac{(-2^{3})}{4}*0,1=

e) (1\frac{1}{3})^{2}*(-\frac{1}{3})^{-2}-1,9^{0}*3^{-1}=


Rozwiąż równania:
a) \frac{1}{3}x+2=2
b) -7(2x+1)=4

c) \frac{3-x}{2}+ \frac{x+2}{2}=\frac{1}{2}

d)  \frac{1}{4}x- \frac{x-1}{4}= \frac{1}{4}
