2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40

Answer:
t=11,11 days
Step-by-step explanation:
F=frogs poblation, t=time, be the variables dF/dt = KF, dF/F=Kdt, integrating
⇒ LnF=Kt+c,
; Knowing t=0, F=17 and t=6 F=51 (tripling every 6 days (17*3)),
⇒
, so
, now if F=130, t=? we have:

Answer:
Final amount after 4 years will be $5518.
Step-by-step explanation:
From the given question Principal amount in the account of Stan = $4706
and we have to calculate amount after 4 years with 4% interest compounded quarterly.

Here A' = $4706
t = 4 years
n = number of times compounded = quarterly that will be 4
r = .04


So the final amount after four years will be $5518.
