Answer: n = 3; n represents a remainder in a division problem.
Explanation:
1) Finding n:
i) Given: 643 = 4 × 160 + n
ii) Do the operations: 643 = 640 + n
iii) Subraction property of the equality: 643 - 640 = n
iv) Do the operations: 3 = n
Answer: n 3
2) Meaning of n
When you divide 643 by 4 the quotient is 160 and the remainder is 3, because 160 × 4 = 640, and 643 - 640 = 3.
This is, 3 is what is left when you split 643 into 4 getting 160 whole parts (plus the remainder, 3).

The area of the big circle is 415.48 and the smaller one is 59.69 so divide 59.69 by that number and multiply by 100 then do 100- that number(14.37) to get 85.63%
Answer:
Kameron is 50 years old.
Step-by-step explanation:
We can make equations and start filling in what we already know, assuming 
is Niko's age, 
is Lila's age, 
is Amber's age, and 
is Kamerons age.
Our first equation:
n = 3L
We know that Niko is 45, so
45 = 3L
Divide both sides by 3:
L = 15
So, Lila is 15 years old.
Another equation:
n = L + 3a
We already know Niko and Lila's age:
45 = 15 + 3a
Subtract 15 from both sides:
30 = 3a
Divide both sides by 3:
a = 10
So Amber is 10 years old.
Another equation:
k = 2(a + L)
We know Amber and Lila's age:
k = 2(10 + 15)
k = 2(25)
k = 50
So Kameron is 50 years old.

After six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.
<h3>
What is Rate ?</h3>
Rate is a measure or quantity measured against another quantity or measure which is the ratio between two related quantities in different units
It is given that you want to create a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. The costs at two studios are shown.
- Studio B: $6.50 per hour.
Multiply both together. That is,
8 x 6.5 = $52
The two cost will be the same at $52. By that time,
Studio A will be six and half hours.
Studio B will be eight hours.
Therefore, after six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.
