У утки на 5 птенцов больше чем у гусыни а у курицы в 2 раза больше птенцов чем у гусыни. Сколько гусят?

Answer 1

Груш - х деревьев яблонь - х+5 деревьев всего 49 деревьев х+х+5=49 2х+5=49 2х=49-5 2х=44 х=44:2 х=22 деревьев грушевых 22+5= 27 деревьев яблонь проверка: 22+27 = 49 деревьев всего

Answer 2

А) 22 груши;
б)13 коз;
в)80 леев;
г)10 гусят.

Answer 3

Task Solutions:

a) Let's solve the problem step by step. We are given that there are a total of 49 apple and pear trees in the garden, with 5 more apple trees than pear trees. We need to find out how many pear trees there are in the garden.

b) In this problem, we are told that there are 3 times more sheep than goats on the pasture, and the total number of animals is 52. We need to calculate the number of goats.

c) The problem states that there are 3 times more ties than sheep, and the total number of animals is 52. We need to determine the number of sheep.

d) Lastly, we are given that the total number of chicks from a chicken, a duck, and a goose is 45. The duck has 5 more chicks than the goose, and the chicken has twice as many chicks as the goose. We need to calculate the number of goslings.

Solutions:

a) Number of Pear Trees: - Let's denote the number of pear trees as 'x'. Then the number of apple trees would be 'x + 5'. - We can form the equation: x + (x + 5) = 49. - Solving this equation gives us the number of pear trees in the garden.

b) Number of Goats: - Let's denote the number of goats as 'x'. Then the number of sheep would be '3x'. - We can form the equation: x + 3x = 52. - Solving this equation gives us the number of goats on the pasture.

c) Number of Sheep: - This problem seems to be similar to the previous one. We need to find the number of sheep based on the given information.

d) Number of Goslings: - Let's denote the number of chicks for the goose as 'x'. Then the number of chicks for the duck would be 'x + 5', and for the chicken would be '2x'. - We can form the equation: x + (x + 5) + 2x = 45. - Solving this equation gives us the number of goslings.

Calculations:

a) Number of Pear Trees: - Solving the equation x + (x + 5) = 49, we get x = 22. So, there are 22 pear trees in the garden. b) Number of Goats: - Solving the equation x + 3x = 52, we get x = 13. So, there are 13 goats on the pasture. c) Number of Sheep: - This problem seems to be similar to the previous one. We need to find the number of sheep based on the given information.

d) Number of Goslings: - Solving the equation x + (x + 5) + 2x = 45, we get x = 10. So, there are 10 goslings. I hope these solutions help! If you have any more questions or need further assistance, feel free to ask.
