80 * 2^0 = 80*1 = 80g (amount initially)
<span>80 * 1/2 = 40 g (amount remaining after one half life) </span>
<span>80* (1/2)^2 = 80* 1/4 = 20 g (amount remaining after 2 half lives).</span>
Answer:
x = 5
Step-by-step explanation:
6x + 14 = 44
6x = 30
x = 5
The answer is 4. A good way to solve order of operations is through PEMDAS
One possible answer is: √20 ≈ 4.472
Answer:
Parallel lines have the same slope, so you know the equation will be y = 2x + b. Use the point (1,5) to sub in for (x,y) to solve for b. So, the equation will be y = 2x + 3.
