What is natural number in math?
Normative Numbers The numbers we use to count or place things in order are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11. Complete numbers the range of numbers that includes zero and natural numbers.Is zero a natural number?
0 is not a natural number, so no. As we all know, natural numbers are positive integers with a range of 1 to infinity. However, we get a number when we combine 0 with a positive integer like 10, 20, or another number.u = {0, 1, 2, 3, 4, 5, 6, 7, 8}
Odd number less than 8 = { 1,3,5,7 }

Which equation is true when c = 3?
2c + 8 = 31
35 − 5c = 32
9 − 6c = 0
4c + 8 = 20
Answer:
4c + 8 = 20
Step-by-step explanation:
To find which equation is true, we have to plug 3 into x in each equation.
2c + 8 = 31
Plug in 3 into c
2(3) + 8 = 31
6 + 8 = 31
14 = 31
Since 14 doesn't equal 31, this equation isn't true.
35 − 5c = 32
Plug in 3 into c
35 − 5(3) = 32
35 - 15 = 32
20 = 32
Since 20 doesn't equal 32, this equation isn't true.
9 − 6c = 0
Plug in 3 into c
9 − 6(3) = 0
9 − 18 = 0
-9 = 0
Since -9 doesn't equal 0, this equation isn't true.
4c + 8 = 20
Plug in 3 into c
4(3) + 8 = 20
12 + 8 = 20
20 = 20
Since 20 equals 20, this equation is true.

Answer is x ≤ - 4
According to the question ,
- 3 ≥ x + 1
rearrange the equation
x + 1 ≤ - 3
x ≤ - 4 {solution of inequality}
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign
While graphing inequalities, we have to keep the following things in mind.
For graphing inequalities with two variables, you will have to plot the "equals" line and then, shade the appropriate area. There are three steps:
Write the equation such as "y" is on the left and everything else on the right.
Plot the "y=" line (draw a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade the region above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
If the endpoint is included (i.e., in case of ≤ or ≥) use a closed circle.
If the endpoint is NOT included (i.e., in case of < or >), use an open circle.
Use open circle at either ∞ or -∞.
Draw a line from the endpoint that extends to the right side if the variable is greater than the number.
Draw a line from the endpoint that extends to the left side if the variable is lesser than the number.

What is the solution to the compound inequality?Given the data in the question;
-x - 8 ≤ -15 and -18 ≤ -x - 8
To solve, simplify the first part of the inequality by solving for x.
-x - 8 ≤ -15
Add 8 to both sides
-x - 8 + 8 ≤ -15 + 8
-x ≤ -7
Divide both sides by -1
Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.
-x/-1 ≥ -7/-1
x ≥ 7
Next, simplify the second part of the inequality by solving for x
-18 ≤ -x - 8
Rewrite as
-x - 8 ≥ -18
Add 8 to both side
-x - 8 + 8 ≥ -18 + 8
-x ≥ -10
Divide both sides by -1
Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.
-x/-1 ≤ -10/-1

The total cost of the brackets before tax = $89.70
Height = 9 feet
length = 10 feet
Wall brackets come in 48-in cost $12.95 and 60-in costing $16.95
Distance of brackets from ends = 1 foot
Maximum distance between brackets = 24 inches
The brackets are:
48/12= 4feet, and 60/12 = 5feet
One of each must be used to cover the height of the shelf.
The length of the shelf is 60 inches
On subtracting 1 foot from each side of the allowance we get, 60-2 = 58-in
Then dividing by 24 we get
58/24 ≈3

What is Geometric progression?
A sequence in which the ratio of any term and its previous term is equal to a fixed constant called common ratio [r] is called geometric progression. For example -
3, 6, 12, 24, ... and so on.
Given that Quinten shares a secret with his friend and each person that hears the secret shares the secret with a new person each day.
On the first day only 2 people know the secret i.e. Quinten and his close friend. Now, they both will tell one new person on second day, which means that by the end of second day four persons will know the secret. Now, these four persons will share with new individual, this gives us a total of 8 persons, who knows the secret by the end of day three and so on.
Now, we get the following sequence -
2, 4, 8, ...... and on.
Now, we can clearly see that -
4/2 = 8/4 = 2
Therefore, this sequence is a geometric progression with common ratio
r = 2.
Assume the 4th term of GP is x. Therefore -
x/8 = 2

Step-by-step explanation:
what is the equation in point-slope form of the line passing through (0, 5) and (−2, 11)? (1 point) y − 5
y - 11 = -3 ( x + 2) is the equation in point-slope form of the line .
What is slope ?
The inclination of a line with respect to the horizontal is measured numerically. The ratio of the vertical to the horizontal distance between any two points on a line, ray, or line segment is known as its slope in analytic geometry ("slope equals rise over run").Given points : (0, 5) and (−2, 11)
Slope of the line passing through given points
[tex]m = \frac{y_{2}- y_{1} }{x_{2} - x_{1} } = \frac{11 - 5}{-2 - 0} = \frac{6}{-3} = -3[/tex]
Thus, slope of line passing through given points m=-3
We know that the equation of a line passing through points ( x₀ , y₀) with slope 'm' is ( y - y₀ ) = m(x - x₀)
Thus, equation of a line passing through (−2, 11) with slope m=-3 will be
( y - 11 ) = -3 ( x - (-2))
y - 11 = -3 ( x + 2)
Hence, the equation of line is y - 11 = -3 ( x + 2).

The value of 50-cents coins is $21, the value of 10-cents coins is $15 and the value of the 20-cents coins is $14.
Percentage of the number:
Percentage is defined as the a number or ratio that can be expressed as a fraction of 100.
If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
Given,
Roslan had a total of 50$ in 10-cents coins,20- cent coins and 50-cents coins.
The value of his 10- cents coins was 30% of the total value of all his coins.
The value of his 20-cents coins was 28% of the total value of all his coins.
Here we need to find the value of 50-cent coins.
We know that,
Total value = $50
So the value of 10-cent coins
=> 30% × $50 = $15
Then the value of 20-cent coins
=> 28% × $50 = $14
Through the known values of 10-cents and 20-cents we have calculate the value of 50-cents coins as,
=> $50 – $15 – $14 = $21
Therefore, the value of 50-cents coins is $21.
