Question

Вокруг Катиного дома растут 10 берёз, это в три раза меньше, чем тополей, а лип на 15 больше, чем тополей. Сколько берёз, тополей и лип растут вокруг Катиного дома?

Answer 1

1)10*3=30(т)-вокруг Катиного дома
2)30+15=45(л)вокруг Катиного дома
3)10+45+30=85(д)-растут вокруг Катиного дома

Answer 2

1) 10*3=30(т) - тополей
2) 30+15=45(л) - лип
3) 10+30+45=85 (д) - деревьев всего
Ответ : 85 - берез, тополей, лип растут около Катиного дома

Answer 3

Calculation of the Number of Birch, Poplar, and Linden Trees

To determine the number of birch, poplar, and linden trees around Katin's house, we need to analyze the given information.

According to the information provided: - The number of birch trees is three times less than the number of poplar trees. - The number of linden trees is 15 more than the number of poplar trees.

Let's assign variables to represent the number of each type of tree: - Let B represent the number of birch trees. - Let P represent the number of poplar trees. - Let L represent the number of linden trees.

Based on the given information, we can set up the following equations:

1. The number of birch trees is three times less than the number of poplar trees: B = P/3.

2. The number of linden trees is 15 more than the number of poplar trees: L = P + 15.

To find the values of B, P, and L, we can solve these equations simultaneously.

Let's substitute the value of B from equation 1 into equation 2:

L = (P/3) + 15.

Now, we can solve this equation to find the value of P:

(P/3) + 15 = P.

Multiplying through by 3 to eliminate the fraction:

P + 45 = 3P.

Simplifying:

2P = 45.

Dividing both sides by 2:

P = 22.5.

Since we cannot have a fractional number of trees, we can round P to the nearest whole number:

P ≈ 23.

Now, we can substitute the value of P into equation 1 to find the value of B:

B = 23/3.

Rounding B to the nearest whole number:

B ≈ 8.

Finally, we can substitute the value of P into equation 2 to find the value of L:

L = 23 + 15.

L = 38.

Therefore, around Katin's house, there are approximately 8 birch trees, 23 poplar trees, and 38 linden trees.
