Answer:
Amanda found the equation 10x+5y=20 in the “linear equations” chapter of her math book.
Step-by-step explanation:
Answer: 0.8(.50)^t/5
P(t)= p^0(1+-r)^t
0.8= initial mass
.50= 100/2-> halving
t/5= how many times for every 5 days
assuming each grid is 1
period = 11 - 1
= 10
x=2.5
5x<12 1. /5 on both sides
x= 2.5
i'm not sure but i think its 7,14,21
7,14,21
