Answer:
It C - S = 1520
Step-by-step explanation:
The way i founded it out was
r = 1369/1521 ≈ 0.90 these the common ratio
So, the sum is ...
S = 1521/(1 -r) = 1521/0.10 = 15,210 . . . . . sum of the series
Based on the formula given of 27π = πn, we can find the value of n after substitution in an equation to be 27.
<h3>What is the value of n?</h3>
The value of n can be found by making n the subject of the formula as shown below;
27π = πn
n = 27π / π
Solving of n therefore gives:
n = 27π/π
n = 27
In conclusion, n is 27.

Answer:
10 or -2 (Both work)
Step-by-step explanation:
Solve the equation |x - 4| = 6:
|x - 4| = 6
Now do the inverse operation of negative 4 to get positive 4.
|x - 4| = 6
+ 4 + 4
|x| = |10|
x = 10
The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
a. Write an equation that shows the amount of dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
The equation is y = -3/2x + 30
b. Explain the meaning of the negative slope above.
As the number of car washes increase, the dollars left on the card decreases.
c. What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2
x = 20
