3x+3(x+12)=84
x= # of brownies originally sold.
Answer:
x=2.5
Step-by-step explanation:
Half of the starting amount remains after 1 half-life. So after 6 half-lives, the starting amount is halved 6 times, meaning that a 195 g sample would decay down to
(195 g)/2^6 = 195/64 g ≈ 3 g
Answer:
Slope is 3/2
y-intercept is (0,-45)
6.46 is greater than 4.6.
