Keagan Brady · Answer 1

L = 80.2 + 2 (0.4)

(b) No, one linear equation will be sufficient to solve the problem. Because it is not two statements of equation

Step-by-step explanation:

Between 1996 and 2005, there is 10 years difference.

It is given in the question that the life expectancy increases by 0.4 every five years.

Between 1996 and 2005, life expectancy of woman born will increase by 2x0.4 = 0.8.,

In 2005, the life expectancy of woman born is:

L = 80.2 + 0.8 = 81.0 years
