The negative number - 7 and its opposite number 7 are represented on the number line.
What is a number line?A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.
Point D represents a negative number which is -7.
We know that if the number is 'a', then the opposite number of the number 'a' will be '-a'.
Then the point representing the opposite of that number will be given as,
⇒ -(-7)
⇒ 7

How do you convert from a radical expression to a rational exponent?
Im just a little confused so if someone could explain this to me, thatd be great!
To convert a radical expression to a rational exponent, identify the root index of the radical as this will be the denominator of the rational exponent. The base remains unchanged. The rational exponent is 1 over the root index.
Explanation:To convert a radical expression to a rational exponent, you need to understand the connection between them. In mathematics, the 'nth root of a' can be written as a radical expression or as a to the power of 1/n, which is the rational exponent form.
For example, if we have √a (square root of a), which is a radical expression, it can be written as a^(1/2) in rational exponent form. Similarly, the cube root of a (3√a) translates to a^(1/3).
Here are the steps for conversion:

Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators. He has 72 pencils and 24 calculators and he must use all of the pencils and calculators. If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?
Answer:
3 pencils
Step-by-step explanation:
We are given Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
Number of pencils=72
Number of calculators=24
If Zayed creates the greatest number of identical packages
Then , we find GCF of 72 and 24
[tex]72=2\times 2\times 2\times 3\times 3[/tex]
[tex]24=2\times 2\times 2\times 3[/tex]
GCF=[tex]2\times 2\times 2\times 3[/tex]

Which of the following approaches can be used to construct a parallelogram? Select one: a. Measure equal segments on parallel lines, then join the endpoints of these segments. b. Construct two congruent angles, then bisect them. c. Construct the perpendicular bisector of a segment, then bisect two of the right angles. d. Construct two perpendiculars to a parallel line.
Final answer:
The correct approach to constructing a parallelogram is to measure equal segments on parallel lines and then join the endpoints of these segments, which ensures opposite sides are equal and parallel.
Explanation:
The student has asked which of the following approaches can be used to construct a parallelogram. The correct approach is Measure equal segments on parallel lines, then join the endpoints of these segments, which corresponds to option a. This method utilizes the properties of parallelograms, where opposite sides are equal in length and parallel to each other. The Euclidean Geometry postulates that relate to this method include E1 Two points determine a line, E2 Line segments can be extended, and the Parallel postulate: Given a line and a point not on the line, no more than one line can be drawn through the point and parallel to the given line.
To construct a parallelogram, you can follow these simplified steps:
Select any two parallel lines.
Measure and mark equal length segments on each of the lines.
Join the corresponding endpoints of these segments to form the parallelogram.

solve the inequality 2(p – 7) > 8
The solution to the given inequality 2(p – 7) > 8 is p > 11.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The inequality is given in the question following as:
2(p – 7) > 8
We have to determine the solution to the given inequality.
As per the question, we have
2(p – 7) > 8
Open the parentheses and apply the distributive property of multiplication,
2p - 14 > 8
Add 14 both sides of the above in inequality,
2p - 14 + 14 > 8 + 14
2p > 22
Divided by 2 into both sides of the above in inequality,
p > 11
Therefore, the solution to the given inequality is p > 11.

A soccer team played 160 games and won 65 percent of them. How many games did it win ? Please show work
The number of games won is 104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of games = 160
Percentage of games won = 65%
Now,
The number of games won.
= 65% of 160
= 65/100 x 160
= 104
Thus,
The number of games won is 104.

7 < h < 9
7 > h > 9
h < 7 or h > 9
h > 7 or h < 9
Answer:
Option C is correct.
The inequalities can be written as one statement as : h<7 or h>9
Step-by-step explanation:
Let h be the working hours
Antonio can drive home after working less than 7 hours.
Less than symbol represented by ('<')
then, we have h<7
Antonio after working more than 9 hours.
More than symbol represented by ('>').
then, we have h>9
Since, we use inequalities when there is a range of possible answers for a given situation
Now, as per the given statement,

Which are correct representations of the inequality 6x ≥ 3 + 4(2x – 1)? Check all that apply.
A=1 ≥ 2x
B=6x ≥ 3 + 8x – 4
and on a graph
.5 shaded to the left
- .5 shaded to the right
.5 shaded to the right
checking all that apply the correct answers would be A B and C
The correct answers are:
A) 1 ≥ 2x ; B) 6x ≥ 3 + 8x – 4 ; and .5 shaded to the left
Explanation:
Our inequality given is 6x ≥ 3 + 4(2x - 1). First we use the distributive property:
6x ≥ 3 + 4(2x) + 4(-1)
6x ≥ 3 + 8x - 4
This means A is correct.
Next we can subtract 8x from each side:
6x-8x ≥ 3+8x-4-8x
-2x ≥ 3-4
-2x ≥ -1
Divide both sides by -1 (remember to flip the inequality symbol):
-2x/-1 ≥ -1/-1
2x ≤ 1
This can also be written as 1 ≥ 2x, so B is correct.
To finish solving this, divide both sides by 2:
2x/2 ≤ 1/2
x ≤ 0.5
To graph this, we circle 0.5 and fill it in (since it is less than or equal to), and shade to the left (since it is less than).
