World population in 2013 was about 7.125 billion
In 2003 , it was about 6.357 billion
Increase = 2013 population- 2003 population
That’s 7.125 billion - 6.357 billion = 0.768 billion

Answer:
Solution: 
, 3.5, -15, 5
Not a solution: 129 and 
Step-by-step explanation:
20 ≥ 5 + 3x
3x + 5 ≤ 20
3x ≤ 20 - 5
3x ≤ 15
x ≤ 5
x must be LESS than or EQUAL to 5
