Answer:
$8,466.15
Step-by-step explanation:
X equals -1.
y equals -9
simply plug 5x-4 into 7x-3y=20.
which is 7x-3(5x-4)=20
28/14 divided by 7/7 = 4/2 divided by 2/2 = 2/1 = 2
Answer:
The answer is B!
Step-by-step explanation:
Add 1 to both sides, then divide 80 by 9!
The indicated sum for the geometric series is 121.5
<h3>How to identify the indicated sum for the
geometric series?</h3>
The series is given as:
162 − 54 + 18 − 6 + .....
Start by calculating the common ratio of the geometric series.
This is calculated using
r = -54/162
Evaluate
r = -1/3
The indicated sum for the geometric series is then calculated as:
S = a(1 - r^n)/1 - r
Substitute the known values in the above equation
S = 162(1 - (-1/3)^7)/1 + 1/3
Evaluate the exponent and the sum
S = 162(1 + 1/2187)/4/3
Evaluate the sum
S = 162(2188/2187)/4/3
Express as products
S = 162 * (2188/2187)* 3/4
Evaluate the product
S = 162 * 547/729
Evaluate the product
S = 121.5
Hence, the indicated sum for the geometric series is 121.5
