Answer:
x = -3
Step-by-step explanation:
Given expression is,
[tex]\frac{2}{x}- \frac{4x}{2x-3}=-2[/tex]
[tex]\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2[/tex]
[tex]\frac{2(2x-3)-4x^{2} }{x(2x-3)}=-2[/tex]
(4x - 6) - 4x² = -2x(2x - 3)
4x - 6 - 4x² = -4x² + 6x
4x - 6 = 6x
6x - 4x = -6
2x = -6
x = -3

The left side is equal to 8x+2 (2x1=2 2x=2x 2x+6x=8x) so the right side needs to be equal to 8x+2 too. The 2 is already there, but you need to multiply 4 by something to get 8x. Option 1 or A would not work because it would only create 4x. Option 3 or C would not work because it would create 12x which is too high.
A running track has 2 semicircular ends of radius 63 m and two

Answers
Answer:
437
Step-by-step explanation:
Because if you multiply 63 x 2 = 126
then subtract that from 1000

Ron traveled 6.8 miles of his delivery route in 12 hours. At this same rate, which of the following is closest
to the time it will take for Ron to travel 20 miles?
O 3 hours
O 3.5 hours
O 6 hours
O 6.5 hours
Answers
Answer:
6.5 Hours
Step-by-step explanation:
If it takes Ron 12 hours to go 6.8 miles then 8 hours more is only 1.7 miles an hour. It will take him well over 6.5 hours to do 20 miles so 6.5 hours is the closest answer
The time that should be taken for Ron to travel 20 miles in 3.5 hours.
Given that
Ron traveled 6.8 miles in 1.2 hours.
We need to find out the time that should be taken for Ron to travel 20 miles.
So, the time taken should be
[tex]= \frac{20\ miles \times 1.2\ hours}{6.8\ miles}[/tex]
= 3.5 hours
Here we assume that time should be 1.2 hours instead of 12 hours.
Therefore we can conclude that The time that should be taken for Ron to travel 20 miles in 3.5 hours.

At the Henry Doorly Zoo the giraffe grew from 24 inches to 60 inches long in five months. Find
the percent of change and show your work clearly. Is this a percent increase or percent
decrease?
Answers
Answer:
150%
It is a percentage increase
Step-by-step explanation:
We start by calculating the percentage increase
Mathematically, we have this as;
Percentage increase = (new value - old value)/old value * 100%
New value = new height = 60 inches
old value = old height = 24 inches
Substituting these values, we have ;
(60-24)/24 * 100%
= 36/24 * 100%
= 1.5 * 100% = 150%
It is a percentage increase as we can see growth

Jessica conducts an experiment. She flips a coin 100 times. In her experiment, she gets heads 40 times and tails 60 times. Based on her results, if she flipped the coin another 50 times, she should expect to flip heads _____ times.
Answers
Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.
If the x-axis is the perpendicular bisector of a segment with an endpoint of (2,3) what are the coordinates of the other endpoint of this segment?
Answers
Answer:
(2, -3)
Step-by-step explanation:
The x-axis is the perpendicular bisector of a segment with an endpoint of (2,3).
A perpendicular bisector is a line which is perpendicular to a segment, dividing the segment into two equal parts. The perpendicular bisector passes through the midpoint of the segment.
Since the x axis bisects a segment with an endpoint of (2,3) perpendicularly, hence a point on the x axis is the midpoint of the segment. The midpoint would have the same x coordinate as the endpoint.
Hence, the midpoint is (2, 0).
Let (x, y) be the other endpoint, then:
(2, 0) is the midpoint of the segment joining (2, 3) and (x, y). we find the value of x and y using:
(2 + x) / 2 = 2; and (3 + y) / 2 = 0
2 + x = 4; and 3 + y = 0
x = 4 - 2 ; and y = 0 - 3
x = 2; and y = -3
Hence the other endpoint is at (2, -3)
Because the x-axis is the perpendicular bisector of a segment with an endpoint of (2, 3), we will see that the other endpoint must be at (2, -3).
How to find the other endpoint?First, we know that the x-axis is perpendicular to our segment, so our segment must be a vertical segment. This means that there can't be a variation in the x-values between the endpoints.
So, if one endpoint is (2, 3), then the other must be (2, y).
To find the value of y we use the fact that the x-axis is also a bisector, so it divides the segment in two equal parts, then we must have y = -3
In this way, we can conclude that the other endpoint is (2, -3)

The perimeter of a rectangle is 27 inches. The ratio of length to width is 2:1. What are the length and width of the rectangle? Round answers to the nearest tenth.
Answers
Perimeter is the sum of the two lengths plus the sum of the two widths.
Divide the perimeter in half and that is the sum of one length and one width.
27/2 = 13.5
The ratio is 2:1, add the ratio: 2 +1 = 3
Divide the sum by 3:
13.5/3 = 1.5
Multiply that the each portion of the ratio:
4.5 x 2 = 9
4.5 x 1 = 4.5
The length is 9 inches
The width is 4.5 inches
