Answer:
x divided by 75% = y
Step-by-step explanation:
Answer:
0.31 yr
Step-by-step explanation:
The formula for interest compounded continuously is

FV = future value, and
PV = present value
If FV is twice the PV, we can calculate the doubling time, t

1. Brianna's doubling time

2. Adam's doubling time
The formula for interest compounded periodically is

where
n = the number of payments per year
If FV is twice the PV, we can calculate the doubling time.

3. Brianna's doubling time vs Adam's
10.663 - 10.355 = 0.31 yr
It would take 0.31 yr longer for Brianna's money to double than Adam's.
5x-y10 We're basically just multiplying the 5 by x and the y by 5 and -2.
(5/x= 5x) + (y/-2/-5)
A) 20.6 x 11.4 : 21 x 11 = 252
6.9 x 3.6 : 7 x 4 = 28
252/28 = 9
b) Each number has been multiplied by 10 so for 4 numbers 9 x 10000 = 90000
