Question

(21,6-12,6):(18+6)= Уравнение: (1,4+2,6)*х-10,12:4=3,47 (0,06:х)+4,14=10,002

Answer 1

Решение первого и второго примерчиков во вложении. В третьем по моему ошибка в условии

Answer 2

1)=0,375

Уравнение:

(1,4+2,6)×х-10,12÷4=3,47

х=1,5

4,0х=10,12/4=3,47

4,0х=3,47+10,12/4

4х=6

х=6/4=1,5

а второе не смог

Answer 3

To solve the equations, let's break them down one by one.

1. (21,6-12,6):(18+6)

First, perform the operations inside the parentheses:

(21.6 - 12.6) = 9 (18 + 6) = 24

Now, perform the division:

9 ÷ 24 ≈ 0.375

2. Уравнение: (1,4+2,6)*х-10,12:4 = 3,47

First, perform the operations inside the parentheses:

(1.4 + 2.6) = 4

Now, the equation becomes:

4 * x - 10.12 ÷ 4 = 3.47

Next, perform the division:

10.12 ÷ 4 ≈ 2.53

Now, the equation is:

4 * x - 2.53 = 3.47

To isolate x, we need to move the constant terms to the other side:

4 * x = 3.47 + 2.53 4 * x = 6

Finally, solve for x:

x = 6 / 4 x = 1.5

3. (0,06:х) + 4,14 = 10,002

First, perform the division:

0.06 ÷ x

Now, the equation becomes:

(0.06 ÷ x) + 4.14 = 10.002

To isolate (0.06 ÷ x), we need to move the constant term (4.14) to the other side:

(0.06 ÷ x) = 10.002 - 4.14 (0.06 ÷ x) = 5.862

Next, we can solve for x by taking the reciprocal of both sides:

x = 0.06 ÷ 5.862

x ≈ 0.010236

So, the solutions to the equations are:

1. (21,6-12,6):(18+6) ≈ 0.375
2. x ≈ 1.5
3. x ≈ 0.010236
