Question

Реши задачу. Ты В парке растут ели, липы и сосны. Сосен И ЛИП Вместе 400, сосен и елей - 300, елей и лип - 440, Сколько в парке елей, сколько лип и сколько сосен? с офарслением задачи​

Answer 1

Ответ:

170 елей, 130 сосен, 270 лип.

440 -400 = 40 (деревьев) - на столько больше елей чем сосен

(300 - 40)/2=130(деревьев) - сосен

300-130=170(деревьев) - елей

440 - 170=270(деревьев)- лип

Answer 2

Problem Analysis

The problem states that there are three types of trees in the park: spruce, linden, and pine. The total number of spruce and linden trees combined is 400, the total number of spruce and pine trees combined is 300, and the total number of pine and linden trees combined is 440. We need to determine the number of spruce, linden, and pine trees in the park.

Solution

Let's assume the number of spruce trees is S, the number of linden trees is L, and the number of pine trees is P.

From the given information, we can form the following equations:

1. S + L = 400 (Equation 1) 2. S + P = 300 (Equation 2) 3. P + L = 440 (Equation 3)

To solve this system of equations, we can use substitution or elimination method. Let's use the elimination method.

Adding Equation 1 and Equation 2, we get:

2S + L + P = 700 (Equation 4)

Subtracting Equation 3 from Equation 4, we get:

2S + L + P - P - L = 700 - 440

Simplifying, we have:

2S = 260

Dividing both sides by 2, we find:

S = 130

Now, we can substitute the value of S into Equation 1 to find L:

130 + L = 400

Simplifying, we have:

L = 400 - 130 = 270

Finally, we can substitute the values of S and L into Equation 3 to find P:

P + 270 = 440

Simplifying, we have:

P = 440 - 270 = 170

Therefore, there are 130 spruce trees, 270 linden trees, and 170 pine trees in the park.

Answer

In the park, there are 130 spruce trees, 270 linden trees, and 170 pine trees.
