Будь ласка порахуйте рівняння.33m-m=102,4;2,7x-1,3x+3,6x=2.Будь ласка поможіть.​

Answer 1

Ответ:

Пошаговое объяснение:

32m = 102,4

m = 102,4 : 32

m = 3,2

5x = 2

x = 2 : 5

x = 2/5

Answer 2

Solving the equation 33m - m = 102.4:

To solve the equation 33m - m = 102.4, we can combine like terms on the left side of the equation:

33m - m = 102.4 (33 - 1)m = 102.4 32m = 102.4

Now, we can isolate the variable m by dividing both sides of the equation by 32:

32m/32 = 102.4/32 m = 3.2

Therefore, the solution to the equation 33m - m = 102.4 is m = 3.2.

Solving the equation 2.7x - 1.3x + 3.6x = 2:

To solve the equation 2.7x - 1.3x + 3.6x = 2, we can combine like terms on the left side of the equation:

2.7x - 1.3x + 3.6x = 2 (2.7 - 1.3 + 3.6)x = 2 4x = 2

Now, we can isolate the variable x by dividing both sides of the equation by 4:

4x/4 = 2/4 x = 0.5

Therefore, the solution to the equation 2.7x - 1.3x + 3.6x = 2 is x = 0.5.
