The equation is 20x = 1200
x=1200÷20
x=60 rows
Answer:x=2
Step-by-step explanation:
-3x-9=-15
-3x=-6
x=2
The population of the fish is given by P(t) = 750(1 + 0.083)^t; where t is the number of years after 2005.
Here, t = 2050 - 2005 = 45
Population in 2050 = 750(1.083)^45 = 750(36.16) = 27,123
Marked(10)/total = 3/20 (from sample)
total/10 = 20/3 (inverting the above proportion)
total = 10•20/3 = 200/3 ≈ 67
X= 3x + 6 / 3 = 6 (im pretty sure)
