Initial population of rainbow smelt: 227.
Initial population of bloater fish: 1,052.
t - number of the years;
The equation is:
227 - 19.76 t = 1,052 - 92.57 t
92.57 t - 19.76 t = 1,052 - 227
72.81 t = 825
t = 825 : 72.81
t = 11.33 years = 11 1/3 years = 11 years 4 months
Answer: After 11 years and 4 months.
98.07. its a longer number but thats it for short.
- 133 > -7(2x+3)
-133 > -14x - 21
-133 + 21 > -14x
-112 > -14x │ × (-1)
112 < 14x
14x > 112
x > 112/14
x > 8
