Answer 1

Ответ:

Пошаговое объяснение:

210c+73,2=976,2;

210с = 976,2-73,2;

210c = 903;

c=903:210

c=4.3.

******************

16–3,9p=7,42;

-3.9p=7.42-16;

-3.9p = −8,58;

p=-8.58/(-3.9);

p= 2.2.

*********************

9,7x–9,2x–0,2=0,4564;

0.5x = 0.4564+0.2;

0.5x = 0,6564;

x= 0,6564;/0.5;

x= 1.3128.

********************

6(3,5x+2,7)+8,3x=104,1;

21x+16.2 + 8.3x=104.1;

21x+8.3x = 104.1-16.2;

29.3*x = 87.9;

x=87.9/29.3;

x=3.
