Ответ:

[tex]x =19 \frac{19}{125} [/tex]

[tex]x=40 \frac{112}{125} [/tex]

Пошаговое объяснение:

[tex]1)x \div 0.56 = 34.2 \\ x \div \frac{14}{25} = 34.2 \\ x \times \frac{25}{14} = 34.2 \\ \frac{25}{14} x = 34.2 \\ x = \frac{14}{25} \times 34.2 \\ x = \frac{14}{25} \times \frac{171}{5} \\ x = \frac{14 \times 171}{25 \times 5} \\ x = \frac{2394}{125} \\ x = 19 \frac{19}{125} [/tex]

2)(x+587/25)÷13/50=1328/5

(x+587/25)×50/13=1328/5

50/13x+1174/13=1238/5

250x+5870=16094

250x=16094-5870

250x=10224

x=10224÷250

x=10224/250

x=5112/125

x=40 112/125
