First, distribute the left side. You should get 4x-8-2x+4=4x-8. Then, get all the xs on one side.
4x-2x-4x-8+4=-8
Then, put the numbers on one side.
4x-2x-4x=-8+8-4
Then, add it up.
-2x=-4
Then, solve for x.
(-2x)/(-2)=(-4)/(-2)
x=2
Hope that helps!
You have to use the formula cost over quantity
Divide 8 and $2.88
The answer is.
0.36
It triples in size every 4 days. In 16 days it will be 3 * 3 * 3 * 3 times bigger.
3 * 3 * 3 * 3 = 81
Therefore, after 16 days, the colony will contain (81 * 150) or 12,150 microorganisms.
