The first step to finding the answer to this question is to move the constant to the right side and then change its sign.
9n = 92 + 16
Now add the numbers
9n = 108
Finally,, divide both sides of the equation by 9 to find out the answer to your question
n = 12
This means that the correct answer to your question is n = 12.

Answer:
The interest rate was of 5.5% a year.
Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
In this question, we have that:
We have to find r.
Taking the square root from both sides to isolate r.
The interest rate was of 5.5% a year.
Fair spinner contains: A, B, C, D
fair dice contains: 1, 2, 3, 4, 5, 6
There are 10 outcomes in total
1/10 chance to land on B and 3/10 chance to land on and even number.
If you add those it would be
1/10 + 3/10 = 4/10
4/10 = 2/5
The probability of landing on B and an even number is 2/5.
(I just started learning probabilities so please correct me if im wrong ;v;)
Subtract the difference from the total, then divide by 2, that would be the age of the youngest, then add the difference to that for the age of the oldest.
37 - 5 = 32
32 / 2 = 16
The youngest is 16.
16 + 5 = 21
The oldest is 21.
The ages are 16 and 21.
