Question

Помогите решить задачу! По задаче составить уравнение. Рыбаки выловили всего 324 рыбы. Из них окуней в 3 раза больше, чем щук, но на 17 меньше, чем лещей. Сазанов в 2 раза больше чем лещей. Сколько щук выловили рыбаки? сазанов?

Answer 1

X-щука
3x-окунь
3x+17-лещ
2*(3X+17)-сазан
всего: 324
уравнение
x+ 3x+3x+17+2*(3x+17)=324
7x + 17+6x+34=324
13x +51=324
13x=324-51
13x=273
x=273: 13
x=21
3x=63
3x+17=80
2*(3x+17)= 160

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of pikes (щук) caught by the fishermen. We are given the total number of fish caught, which is 324. We also have information about the number of perch (окуней), pikes, and tench (лещей) caught, as well as the fact that the number of pikes is 17 less than the number of tench, and the number of pikes is three times the number of perch. Additionally, we know that the number of carp (сазанов) is twice the number of tench.

Let's assign variables to the unknown quantities: - Let's call the number of perch P. - The number of pikes will be 3P, as it is three times the number of perch. - The number of tench will be T. - The number of carp will be 2T.

Formulating the Equation

We can now set up an equation based on the given information. The sum of the number of perch, pikes, tench, and carp should equal the total number of fish caught, which is 324.

P + 3P + T + 2T = 324

Simplifying the equation, we get:

4P + 3T = 324

Solving the Equation

To find the number of pikes, we need to solve the equation. However, we need another equation to determine the values of P and T. Unfortunately, the given information does not provide enough information to create another equation. Therefore, we cannot determine the exact number of pikes caught by the fishermen.

However, we can still solve the equation for P in terms of T or vice versa. Let's solve the equation for P in terms of T:

4P + 3T = 324

4P = 324 - 3T

P = (324 - 3T) / 4

Similarly, we can solve the equation for T in terms of P:

4P + 3T = 324

3T = 324 - 4P

T = (324 - 4P) / 3

Using these equations, we can find the number of pikes (щук) caught by substituting the values of P and T into the equation 3P.

Please provide the value of either P or T, and I will calculate the number of pikes caught by the fishermen.
