Answer:
Global life expectancy is the average age that people live to be. This is not a national life expectancy where we look only at one country and is on a global level. The industrial revolution impacted life expectancy by raising wages, living conditions. New technology was invented and many breakthroughs in sanitation were made.
C
5x < 30
Divide each side by 5 to find x
x < 6
The number line needs to show the x represents any number less than 6 (3, 5.5, -1, etc)
C is correct because there is an open circle around 6, and then an arrow pointing towards numbers smaller than 6.
If x is less then or equal to six, you draw a filled in circle around six to show that x can be 6.
Because x is less than 6 and not equal to 6, you draw an open circle to represent x can get very close to 6 (ex. 5.9, 5.999) but cannot equal 6.
The line has to be pointing leftwards because the numbers are less then six in that direction. X can be any number smaller than 6, which is how by the leftward arrow
