Response:
The fence's length is expressed as 6.28x - 150 cm.
Detailed Breakdown:
Assuming the circular pool has a radius (r) of x cm.
As the pool is circular, its circumference represents the length of the fence. Additionally, subtracting the 150 cm for the gate gives us the actual length of the fence.
Length of fence = Circumference of pool – gate's width.
Length of fence = 2 π r – 150
Length of fence = 2 × 3.14 × x – 150
Therefore, the fence length is 6.28x – 150 cm.
In the first month, she made a payment of $1451
In the second month, she paid one-third of that, which amounts to:
1451/3 = 483.66
For the third month, she pays one-third of 483.66 as indicated, meaning she takes one-third of the prior month's payment.
483.66/3 = 161.22
In the fourth month, her payment was
161.22/3 = 53.74
Altogether, her total payments amounted to:
$2149.62 - B.

BD=7x-10
Solution: x=bd/7 + 10/7
BC=4x-29
Solution: x=Bc/4 + 29/4
CD=5x - 9
Solution: x= cd/5 + 9/5
A) The first because it features a valency of +1.
b) The seventh because it has a valency of -1.
c) The third as it contains a valency of +3.
