Hope this helped if it did plz give me brainiest Thanks <3
Answer:
x=(-9)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(−2/3)(9+x)=0
(−2/3)(9)+(−2/3)(x)=0(Distribute)
−6+−2/3x=0
−2/3x−6=0
Step 2: Add 6 to both sides.
−2/3x−6+6=0+6
−2/3x=6
Step 3: Multiply both sides by 3/(-2).
(3−2)*(−2/3x)=(3−2)*(6)
x=−9
Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24
The answer is 73.24 years.
