Question

Пж помогите вокруг школы посадили ели и шиповники всего 540 растений шиповников было в 2 раза больше чем елей сколько посадили растений?

Answer 1

1) 2х+х=540
3х=540
х=540:3
х=180 ( раст.) - елей;
2) 180•2=360( раст.) - шиповников.

Answer 2

Calculating the Number of Plants

To calculate the number of plants, we can use the information provided. Let's denote the number of pine trees as P and the number of hawthorn bushes as H. We are given that the total number of plants is 540, and the number of hawthorn bushes is twice the number of pine trees. We can set up the following equations:

1. P + H = 540 (total number of plants) 2. H = 2P (number of hawthorn bushes is twice the number of pine trees)

Solving for the Number of Plants

We can solve this system of equations to find the values of P and H.

Substituting the value of H from equation 2 into equation 1: P + 2P = 540 3P = 540 P = 540 / 3 P = 180

So, the number of pine trees is 180.

Substituting the value of P back into equation 2 to find H: H = 2 * 180 H = 360

So, the number of hawthorn bushes is 360.

Conclusion

Therefore, the number of pine trees planted is 180, and the number of hawthorn bushes planted is 360.
