X=12.5
If the perimeter is 90
90=3x+3x+15
Combine like terms
90=6x+15
Subtracts 15 from both sides
75=6x
Divide by six to get x by itself
12.5=x
Does this help?
Whatever that person said lol
Compound Interest Formula: A = P(1 + r/n)^(n·t)
A = final amount r = rate, as a decimal (.021) t = number of years (17)
P = initial amount (2914.72) n = number of times compounded per year (365)
A = 2914.72(1 + .021/365)^(365·17) = $4165.20
Interest earned: $4165.20 - $2914.72 = $1250.48 <----- Answer
You might want to recalculate this, attempting to handle leap years, by replacing the number of times compounded per year with 365.25 and see if that has an effect
Answer: 3 days in they will bot charge 39$
Step-by-step explanation:
Biking shack= 21+6d(d for days)
Bike nation=12+9d
