Answer 2

0,34х=5,78

х=5,78:0,34

х=17

ОТВЕТ: х=17

4,2х=42,21

х=42,21:4,2

х=10,05

ОТВЕТ: х=10,05

5,2х=42,25

х=42,25:5,2

х=8,125

ОТВЕТ: х=8,125

Answer 3

It looks like you have provided three equations with variables (x) and constants on the right side. You want to solve for the value of x in each equation. Let's solve them one by one:

1. 0.34x = 5.78 To solve for x, divide both sides of the equation by 0.34: x = 5.78 / 0.34 x ≈ 17

2. 4.2x = 42.21 Divide both sides by 4.2 to solve for x: x = 42.21 / 4.2 x ≈ 10.05

3. 5.2x = 42.25 Divide both sides by 5.2 to solve for x: x = 42.25 / 5.2 x ≈ 8.13

So, the solutions for the equations are approximately:

1. x ≈ 17
2. x ≈ 10.05
3. x ≈ 8.13
