A geometric sequence has an initial value of 2 and a common ratio of 3. Which formula would be more practical to use if you were looking find the value of the 19th number in the sequence?
Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978

Solve for x - (4x-5y) = (-5y+4)
Answer:
X= 10/3y + -4/3
Step-by-step explanation:
Step One: add -5y to both sides
Step two: divide both sides by -3
Answer:
-x=1 1/3
Step-by-step explanation:
x-(4x-5y)=(5y+4)
x-4x+5y=5y+4
-3x+5y=5y+4
5y-5y=0
-3x=4
x=4÷3

Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters. She wants to sew a fringe around the edge of the bedspread. WHAT LENGTH OF FRINGE DOES REAGAN NEED TO USE?
Answer: 1346cm
Step-by-step explanation:
From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.
This simply means that we have to find the perimeter of the rectangular bedspread and this will be:
= 2(length + width)
= 2(435 + 238
= 2(673)
= 1346cm
The length of fridge needed by Reegan is 1346cm.

The questions aren't well formatted ; from the values that are observable,
Answer:
Coefficient of x = -9.9 ;
Coefficient of x = 75
Coefficient of y = 275
Step-by-step explanation:
Given :
0.8 (2x + x) + 3(7 - 4.1x) = __x + 21
0.8(3x) + 21 - 12.3x = __x + 21
2.4x + 21 - 12.3x = __x + 21
-9.9x + 21 = __x + 21
-9.9
12 1/2 (6x + 22y) = x + y
75x + 275y = x + y

Jim is hoping that a park will be built within 5 miles of his house. If a park is built at the coordinates (12, 10), does that meet Jim’s criteria? Explain.
Answer:
yes 4.4 miles away
Step-by-step explanation:
The park at the coordinates (12, 10) does not meet Jim's criteria of being within 5 miles of his house.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
To determine if the park at coordinates (12, 10) meets Jim's criteria of being within 5 miles of his house,
We need to calculate the distance between Jim's house at the coordinates
(17, 13) and the park at coordinates (12, 10).
We can use the distance formula to calculate the distance between two points in a coordinate plane:
[tex]d = \sqrt{((x_2 - x_1)^2 + (y_2 - y_1)^2)}[/tex]
where d is the distance between the two points:
[tex](x_1, y_1) and (x_2, y_2).[/tex]
Using the coordinates of Jim's house and the park,
We can calculate the distance between them:
d = √((12 - 17)² + (10 - 13)²)
d = √((-5)² + (-3)²)
d = √(25 + 9)
d = √(34)
The distance between Jim's house and the park is √(34), which is approximately 5.83 miles.
This is greater than Jim's criteria of 5 miles, so the park at the coordinates
(12, 10) does not meet Jim's criteria of being within 5 miles of his house.
Thus,
The park at the coordinates (12, 10) does not meet Jim's criteria of being within 5 miles of his house.

0.6125 (or 6,125/1,000)
If you need more help, don't hesitate to ask!
I'm here until 2:30!
May I please have brainliest?
Answer:
80%
Step-by-step explanation:
7/8 = 87.5/100
7/10 = 70/100
new equation: 70 is what percent of 87.5
87.5/100=0.875 so 0.875=1% so now we divide 70 by 0.875
70/0.875=80 so 7/10 is 80% of 7/8
