Question

Зоомагазине 36 птиц попугаев в 2 раза больше чем Соловьёва голуби на 4 больше чем Соловьев Сколько птиц каждого вида была в зоомагазине

Answer 1

Х+2х+4+х=36
4х+4=36
4х=32
х=8 соловьев.
попугаев 8*2=16
голубей 8+4 = 12

Answer 2

Пусть соловьев - х
тогда попугаев 2х, а голубей х+4
получается уравнение х+2х+(х+4)=36
4х+4=36
4х=36-4
4х=32
х=8
1) 2*8= 16 - попугаи
2)8+4=12 - голуби
3) 36 - 28 = 8 - соловьи

Answer 3

Calculating the Number of Birds in the Pet Store

To solve this problem, we can use a system of equations. Let's denote the number of parrots in the pet store as P and the number of doves as D.

We are given the following information: 1. The pet store has 36 parrots, which is twice the number of doves in Solovyov's store. 2. The number of doves in the pet store is 4 more than the number of doves in Solovyov's store.

We can express this information in the form of equations:

1. P = 36 2. P = 2D 3. D = S + 4

Where S represents the number of doves in Solovyov's store.

Solving the Equations

We can use the second equation to express D in terms of P: D = P / 2

Substituting this expression for D into the third equation: P / 2 = S + 4

Now, we can substitute the value of P from the first equation into the equation above: 36 / 2 = S + 4 18 = S + 4 S = 14

So, there are 14 doves in Solovyov's store.

Now, we can use the value of S to find the number of doves in the pet store: D = 14 + 4 D = 18

Finally, we can find the number of parrots in Solovyov's store using the second equation: P = 2 * 18 P = 36

Conclusion

Therefore, there are 36 parrots and 18 doves in the pet store, and 14 doves in Solovyov's store.
