Answer 1

Ответ:

4) 3,8a+4,6a=13,44

    8,4a=13,44

     a=1,6

5) b-0,872b=32

    0,128b=32

     b=250

6) 4,9m - 0,1m = 3,84

    4,8m=3,84

     m=0,8

Answer 2

Solving Equations

Let's solve the given equations step by step.

Equation 1: 3.8a + 4.6a = 13.44

To solve for 'a', we can combine like terms on the left side of the equation: ``` 3.8a + 4.6a = 13.44 8.4a = 13.44 ``` Now, we can solve for 'a' by dividing both sides by 8.4: ``` a = 13.44 / 8.4 a = 1.6 ``` So, a = 1.6.

Equation 2: 5b - 0.872b = 32

To solve for 'b', we can combine like terms on the left side of the equation: ``` 5b - 0.872b = 32 4.128b = 32 ``` Now, we can solve for 'b' by dividing both sides by 4.128: ``` b = 32 / 4.128 b ≈ 7.75 ``` So, b ≈ 7.75.

Equation 3: 4.9m - 0.1m = 3.84

To solve for 'm', we can combine like terms on the left side of the equation: ``` 4.9m - 0.1m = 3.84 4.8m = 3.84 ``` Now, we can solve for 'm' by dividing both sides by 4.8: ``` m = 3.84 / 4.8 m = 0.8 ``` So, m = 0.8.
