СРОЧНОО​

Answer 1

Ответ:

Пошаговое объяснение:

3/2 = 9/(4 + 2x)

3(4+2x) = 18;

12+6x = 18;

6x = 18-12;

6x=6;

x=1.

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

3x / (6/7) = 1 1/6 / (3  1/3);

--------------

1 1/6 / (3  1/3) = 7/6:10/3 = 7/6*3/10 = 7/20=0.35;

----------------

3x : 6/7 = 7/20;

3x = 7/20 * 6/7;

3x = 3/10;

x= 3/10 : 3;

x=3/10 * 1/3 = 1/10 = 0.1.
