2.57982211163 is the answer
Alright, so after a half-life, half of the previous number would be left. So basically,
180 g ← 0 half lives
90 g ← 1 half life
45 g ← 2 half lives
22.5 g ← 3 half lives
11.25 g ← 4 half lives
Therefore, the answer is 11.25 grams
Remove the brackets on the left
10 - 9x + 120 = - 9x You get a bizarre result no matter what you try to do to resolve this. If you say any number will do pick, a number at random for x. Say 10
10 - 90 + 120 = -90 Is this statement true? No. You only need 1 exception but 0 is a popular number to look for answers. Will it work?
10 - 0 + 120 = 0 That doesn't work either.
There is no number you could pick that that would give you anything but 10 + 120 = 0
