Question

1)8.4-х=2,93; 2) х:3,15=2,4.

Answer 1

Відповідь:

Покрокове пояснення:

8.4-х=2,93

x=8.4-2.93

x=5.47

х:3,15=2,4

x=2.4*3.15

x=7.56

Answer 2

Відповідь:

1). 5,47

2). 7,56

Покрокове пояснення:

1). 8.4-х=2,93

-х = 2,93 - 8,4

-х = -5,47

х = 5,47

2). х:3,15=2,4 / *3,15 (домножуємо)

х = 7,56

Answer 3

To solve these equations, we'll isolate the variable x in each case. Let's solve them step by step:

1. 8.4x = 2.93

To isolate x, divide both sides of the equation by 8.4:

8.4x/8.4 = 2.93/8.4

x = 2.93/8.4

x ≈ 0.3488

So the solution to the equation 8.4x = 2.93 is x ≈ 0.3488.

2. x/3.15 = 2.4

To isolate x, multiply both sides of the equation by 3.15:

(3.15)(x/3.15) = (3.15)(2.4)

x = 7.56

So the solution to the equation x/3.15 = 2.4 is x = 7.56.

Therefore, the solutions are:

1. x ≈ 0.3488
2. x = 7.56
