Answer 1

Answer:

10 trees

Step-by-step explanation:

(i)Number of trees planted this year(x)=24

Let the number of trees planted in previous year= y

According to the question,

x=2y+4

Hence,

24=2y+4

2y=20

y=10 trees

Therefore, 10 trees were planted the previous year by the students of class 8.

(ii) We can learn the moral value of planting more trees and showing care and concern towards the environment.
