the answer would be would be D
The formula is
V (t)=V0 (1-r)^t
V (t)?
V0 1000
R 0.05
T 5 years
V (5)=1,000×(1−0.05)^(5)=773.78
Haha, you first start off with adding 3 to both sides, cancelling the -3, and adding it to 9. you end up with 5x=12, in which you divide both sides by 5. you get 2 and 2/5 or 12/5! hope that helps :)
Answer:
uhhhhhhhhhhhhhhhhhhhhhhh
Step-by-step explanation:
G = gallons d = days
10g = 3d
?g = 1d
1g = ?d
-------------
for gallons in a day, divide 10g = 3d by 3
d = 10/3 gallons
3 and 1/3 gallons in a day
---------------
for days per gallon, divide 10g = 3d by 10
g = 3/10 days
1 gallon lasts 3/10 of a day
