Question

3 бизнесмена вложили деньги в совместные предприятия. Первый вложил на 25 млн р меньше чем 2 и 3 вместе а второй на 33 млн р меньше чем 1 и 3 вместе сколько миллионов рублей вложил 3 бизнесмен? ПОЖАЛУЙСТА СРОЧНО НАДО

Answer 1

Х - вложил 1-й бизнесмен
у - вложил 2-й бизнесмен
z - вложил 3-й бизнесмен
составим уравнения:
y+z-25=x
x+z-33=y, подставим значение х во второе уравнение:
(y+z-25)+z-33=у, раскроем скобки и перенесем у,
y+z-25+z-33-у=0
2z-58=0
2z=58
z=58:2
z=29 миллионов вложил 3-й бизнесмен

Answer 2

Calculating the Total Investment of 3 Businessmen in Joint Ventures

To calculate the total investment of the 3 businessmen in joint ventures, we can use a system of equations based on the information provided.

Let's denote the amounts invested by the businessmen as follows: - The first businessman invested x million rubles. - The second businessman invested y million rubles. - The third businessman invested z million rubles.

Based on the given information, we have the following equations: 1. The first businessman invested 25 million rubles less than the sum of the second and third businessmen's investments: x = (y + z) - 25. 2. The second businessman invested 33 million rubles less than the sum of the first and third businessmen's investments: y = (x + z) - 33.

We need to solve these equations to find the values of x, y, and z.

Solving the Equations

Let's solve the system of equations to find the values of x, y, and z.

1. Using the first equation: x = (y + z) - 25. 2. Using the second equation: y = (x + z) - 33.

Substituting the value of y from the second equation into the first equation: x = ((x + z) - 33 + z) - 25 x = x + 2z - 58

Solving for z: z = (x - 58) / 2

Substituting the value of z back into the second equation: y = (x + ((x - 58) / 2)) - 33 y = (2x - 58 + x) / 2 - 33 y = (3x - 116) / 2 - 33 y = (3x - 116 - 66) / 2 y = (3x - 182) / 2

Now we can substitute the values of x and y back into the first equation to solve for z.

Calculating the Total Investment

Using the values of x, y, and z obtained from the equations, we can calculate the total investment of the 3 businessmen in joint ventures.

The total investment is given by the sum of x, y, and z: Total Investment = x + y + z

Let's calculate the total investment based on the values of x, y, and z obtained from the equations.

Conclusion

Based on the given information and the solution to the system of equations, we can calculate the total investment of the 3 businessmen in joint ventures.
