Question

Реши уравнения . х:20=40*3 210:х=420:6 х*110=110 480:х=480 х-260=0 у+0=300 МОЖНО С ОБЪЯСНЕНИЕМ ПОЖАЛУЙСТА! ТО ЕСТЬ КАК РЕШАТЬ В СТОЛБИК ВСЕ УРАВНЕНИЯ

Answer 1

Смотри. сначала решаешь вторую часть т.е 40*3
40*3=120
получаем:
х:20=120
120*20=2400

Answer 2

40*3=120 120:20=6      420:6=70 210:70=3      110:110=1      480:480=1      260*0=260      300-0=300  

Answer 3

Solving the Equations

Let's solve the given equations step by step.

1. Equation 1: - \(x:20=40*3+210\)

To solve for \(x\): - First, we simplify the right-hand side of the equation: \(40*3+210 = 120+210 = 330\). - Then, we solve for \(x\): \(x:20=330\). - Multiplying both sides by 20 gives us: \(x = 330*20 = 6600\).

2. Equation 2: - \(x+110=110+480:x\)

To solve for \(x\): - First, we simplify the equation: \(x+110=110+\frac{480}{x}\). - Subtracting 110 from both sides gives us: \(x = \frac{480}{x}\). - Multiplying both sides by \(x\) gives us the quadratic equation: \(x^2 = 480\). - Taking the square root of both sides gives us: \(x = \pm\sqrt{480}\).

3. Equation 3: - \(x-260=0\)

To solve for \(x\): - Adding 260 to both sides gives us: \(x = 260\).

4. Equation 4: - \(0=300\)

This equation is not solvable as it leads to a contradiction.

5. Equation 5: - \(150:=30\)

To solve for \(x\): - This equation seems to be incorrectly formatted. It's unclear what operation is intended here.

6. Equation 6: - \(560:80=7\)

To solve for \(x\): - This equation is already solved: \(560:80=7\).

7. Equation 7: - \((750 + 700) : (7500 - 700) = 1450 : 50 = 29\)

To solve for \(x\): - This equation is already solved: \((750 + 700) : (7500 - 700) = 1450 : 50 = 29\).

8. Equation 8: - \(10000 + 9999 = 19999\)

This equation is already solved: \(10000 + 9999 = 19999\).

Conclusion

The solutions to the given equations are as follows: 1. \(x = 6600\) 2. \(x = \pm\sqrt{480}\) 3. \(x = 260\) 4. The equation \(0=300\) is not solvable. 5. The equation \(150:=30\) is unclear and cannot be solved directly. 6. \(560:80=7\) 7. \((750 + 700) : (7500 - 700) = 1450 : 50 = 29\) 8. \(10000 + 9999 = 19999\)
