Body, Captain Hook, and Girls in the hood *chefs kiss*

this is the correct way to solve these types of exercises
then we will try to do the same where a is (6+9x) and b is 24

and solve the right inequality for x

subtract 6 for all expression

now divide on 9

ok, this means that the x values will be from -10/3 to 2 including these

solution is the red zone
So is doubling, first off, meaning, if the current amount say P, then when it doubles is 2P, or double that, or P + P, so the rate of growth is 100%, since it's doubling.
and is doing it every 9 hour cycle, thus
we are adding over 200,000 people<span> to this planet every day, or </span>140 people<span> every minute . That equals over </span>70 million<span> more people every year

If it’s referring to 137 out of 1700, divide 137 by 1700 and multiply by 100. same for the other, except you divide 137 by 390.
