Answer 1

Ответ:

6;

Пошаговое объяснение:

1) 4,2:7=3,6:х. 2)x:1,5-35:7

х=5/21*25,2. х: 3/2-5

х=5/21*126/5. х*3/2-5

х=6. 2/3х-5

3) не знаю

4)9,1:y=65:5

65у=45,5

у=7

у =0,7

5)54:2,7=50:x

54х=135

х=5/2 х=∅

Answer 2

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

1. 4,2:7 = 3,6:х2) x:1,5 - 35:7 First, let's simplify each expression separately: 4,2:7 = 4.2 / 7 = 0.6 3,6:2 = 3.6 / 2 = 1.8 Now, we can substitute these values back into the equation: 0.6 - 35:7 35:7 = 35 / 7 = 5 0.6 - 5 = -4.4

2. 40:0,2 = 2:3 In this equation, we need to divide 40 by 0.2: 40 / 0.2 = 200 So, 40:0,2 = 200.

3. 9,1:y = 65:5 Here, we need to find the value of y. To do that, we can cross-multiply: 9.1 * 5 = 65 * y 45.5 = 65y Divide both sides by 65: 45.5 / 65 = y y ≈ 0.7

4. 54:2,7 = 50:x Similarly, we need to find the value of x. Cross-multiplying: 54 * x = 50 * 2.7 Divide both sides by 54: x = (50 * 2.7) / 54 x ≈ 2.5

So, the solutions to the given equations are:

1. -4.4
2. 200
3. y ≈ 0.7
4. x ≈ 2.5
