Ответ:

1)=0,02

2)0,035

3)0,37

4)0,152

Answer 2

Let's solve each of these equations step by step:

1. 0.76 divided by 38: 0.76 / 38 = 0.02

2. 0.385 divided by 11: 0.385 / 11 ≈ 0.035

3. 1.85 divided by 5: 1.85 / 5 = 0.37

4. 1.064 divided by 7: 1.064 / 7 ≈ 0.152

5. 9.45 divided by 3: 9.45 / 3 = 3.15

6. 4.5 - 2.55: 4.5 - 2.55 = 1.95

7. 2 + 3.93: 2 + 3.93 = 5.93

8. 15.96 divided by N equals the percentage value of 2.04. To find N, we can set up an equation: 15.96 / N = 2.04 / 100

Now, we can solve for N: 15.96 / N = 0.0204

Cross-multiply: 15.96 = 0.0204 * N

Now, divide both sides by 0.0204 to isolate N: N = 15.96 / 0.0204 ≈ 780.39

9. 5.18 divided by X equals 5.13 minus 3.65. To find X, we can set up an equation: 5.18 / X = 5.13 - 3.65

First, calculate the right side of the equation: 5.13 - 3.65 = 1.48

Now, we can solve for X: 5.18 / X = 1.48

Cross-multiply: 5.18 = 1.48 * X

Now, divide both sides by 1.48 to isolate X: X = 5.18 / 1.48 ≈ 3.50

10. 1 divided by X equals 0.54 plus 1.96. To find X, we can set up an equation: 1 / X = 0.54 + 1.96

First, calculate the right side of the equation: 0.54 + 1.96 = 2.50

Now, we can solve for X: 1 / X = 2.50

To isolate X, take the reciprocal of both sides: X = 1 / 2.50 = 0.4

So, the solutions are:

1. 0.02
2. 0.035
3. 0.37
4. 0.152
5. 3.15
6. 1.95
7. 5.93
8. N ≈ 780.39
9. X ≈ 3.50
10. X = 0.4
