Yes, you got it! You would need to set the equations equal to each other, because that represents when their populations are the same. Then, solving for x will find the time in months until you reach that equilibrium in population. If you need help solving for x, just comment on this. Hope it helps!
Tan(40)= x/20 => x= tan(40).20= 16,78
Ok done. Thank to me:>
Answer:
y=x3−8
Step-by-step explanation:
You can set up an equation such as 300=100+8x where x is equal to the number of days gone by since birth. The answer would be 25 days.
Answer:

Step-by-step explanation:
The angles add up to 90 degrees.
x + 2x + x + 10 = 90
Combine like terms.
4x + 10 = 90
Subtract 10 from both sides.
4x = 80
Divide both sides by 4.
x = 20
