Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

Answer:
Elephant conservation has been so successful that within many protected areas, the elephant population has grown to numbers that may not be able to be supported in such small, fragmented landscapes. Being confined to small home ranges year-round is causing drastic changes in landscape and biodiversity. Many over-populated protected areas have experienced the conversion from dense woodland areas to sparse shrub-land or even grass-lands because of increased browsing pressure. Since elephants are selective when choosing trees and shrubs to browse, certain species are more threatened by elephant presence than others and are being carefully monitored so that they do not disappear from areas of high elephant density.
