The process is:
C = 2nr
2nr = c
r (2n) = c

That's the answer☝️☝️☝️☝️
or maybe this one
r = 2n + c
sorry, I'm unsure, it has been too long since I studied that...
Answer:
her grandson would be 7 and her granddaughter would be 5.
Step-by-step explanation:
their ages together is 12. we divide that by the two grandchildren, and adjust it to where they are to years apart.
12÷2=6
6+6 + adjusted = 5 and 7.
to fact check 5+7=12, and 7 is two numbers above 5.
Answer: C. $5,470
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $5000
r = 1.8% = 1.8/100 = 0.018
n = 4 because it was compounded 3 times in a year(12/4 = 3 times)
t = 5 years
Therefore,
A = 5000(1 + 0.018/4)^4 × 5
A = 5000(1 + 0.0045)^20
A = 5000(1.0045)^20
A = $5470 to the nearest whole number
A feature of every linear function is that the slope is the same no matter where you are on the line. When given a table of data that you suspect might represent a linear function the slope manifests itself as a constant common difference between successive y -values.
