Answer:
x>−6,x<−12
Step-by-step explanation:
Break down the problem into these 2 equations.
x+9>3x+9>3
-(x+9)>3−(x+9)>3
Solve the 1st equation: x+9>3x+9>3.
x>-6x>−6
3 Solve the 2nd equation: -(x+9)>3−(x+9)>3.
x<-12x<−12
Collect all solutions.
x>-6,x<-12x>−6,x<−12
So you want to know how many times

fits inside

, if so, here's the answer:
First we see that

is equal to <span>4,000,000, and</span>

is equal to 10,000.
Then we divide

, and we get 400, so.
The answer is 400.
