aaaaaaaaaaaaaaaaaaaaaaaaaasssssssssssssssssss

Answer 1

Пошаговое объяснение:

-0,056 : |х| = -0,8

|х| = -0,056 : (-0,8)

|х| = 0,07

х1 = -0,07

х2 = 0,07

-9 5/6х + 1 5/12х + 2 3/4х = 1 7/27

-9 10/12х + 1 5/12х + 2 9/12х = 1 7/27

-8 5/12х + 2 9/12х = 1 7/27

-7 17/12х + 2 9/12х = 1 7/27

-5 8/12х = 1 7/27

-5 2/3х = 1 7/27

-17/3х = 34/27

х = 34/27 : (-17/3)

х = 34/27 * (-3/17)

х = 2/9 * (-1/1)

х = -2/9
