(2x-3)+(6x+7)= 180
(2x•6x)+(-3+7)= 180
(12x)+(4) = 180
12x= 180-4
x= 176/12
x= 14.67
Answer:
2560
Step-by-step explanation:
in every 160 walleye the catch they catch 12.5 of the tagged ones so this is how to calculate it

Answer:
s =5*π/2 km
Step-by-step explanation:
arc length s = rθ
where θ =central angle in radians
r = 5km
θ = 90 degrees = 90 degrees/360degrees * 2π = (2π) = π/2
s =5*π/2 km
