I'm very confused about this, please explain this to me. ​

The equation formed for the expression "The difference of 3 times a number and 12 is -24", is 3x - 12 = - 24, which gives the number, x = -4.

In the question, we are asked to write and solve an equation to find the number, given that the difference between 3 times the number and 12 is -24.

We assume the number to be x.

The sentence given to us is the difference between 3 times the number and 12.

Three times the number is 3x.

The difference between 3 times the number and 12 can be shown as 3x - 12.

We are given that the difference between 3 times the number and 12 is -24.

This can be shown as 3x - 12 = - 24.

This is the required equation.

To solve this, we do the following steps:

3x - 12 = -24.

Adding 12 to both sides, we get:

3x - 12 + 12 = - 24 + 12,

or, 3x = -12.

Now, we divide both sides by 3, to get:

3x/3 = -12/3,

or, x = -4.

Thus, the equation formed for the expression "The difference of 3 times a number and 12 is -24", is 3x - 12 = - 24, which gives the number, x = -4.

The required percentage of US states having their names starting with W is 8 %. This is gained by using the concept of percentage.

What do you mean by percentage?

The percentage is usually denoted by the symbol '%'. It is defined as the quantity or ratio which is being expressed in a fraction of 100, where 100 is the denominator.

Calculation of the percentage of US states having their names starting with W

Given:

Total states in US = 50

US states that start with the letter W = 4

Fraction in favour of the names of states starting with the letter W is given by = 4 / 50

Therefore the percentage of US states having their names starting with the letter W is equal to the fraction in favour * 100 %

= 4 / 50 * 100 %

= 4 * 2 %

= 8 %

Hence, the percentage of US states having their first letter as W is 8 %.

The area of parallelogram is Base(B) × Height(H).

The quantity of square units that make up a polygon determines its area. Similar to a carpet or area rug, area is two dimensional.

A parallelogram is a four-sided structure made up of two parallel line pairs. The length of opposing sides and the magnitude of opposing angles are both equal. Multiply the base by the height to determine the area. The equation is:

A = B × H,

where B stands for base

H for height

A parallelogram must have a perpendicular base and height. A parallelogram's lateral sides aren't parallel to the base, though. As a result, the height is represented by a dotted line. Let's examine a few instances when the area of a parallelogram is involved.

The  three segments  of Triangle is (1) 17 cm, 7 cm, 8 cm    

Here, 17 > 7 + 8 or 17 > 15

In any triangle, the sum of the lengths of any two sides of a triangle is always greater than the third side.

Therefore, the triangle is not possible.    

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of the geometry is the Euclidean plane, however, this is no longer true in higher-dimensional Euclidean spaces.

Answer:

5p^3q ( 8p^3 + 3p^2q^3 +7q)

Step-by-step explanation:

greatest common factor = GCF

40p^6q + 15p^5q^4 + 35p^3q^2

This expression has 3 terms: 40p^6q , 15p^5q^4 , and  35p^3q^2

Find the GCF for the 3 terms

The coefficient parts are 40, 15 and 35 their GCF is 5

The p part: p^6, p^5, and p^3 their GCF is p^3

The q part: q, q^4, and q^2 their GCF is q

The GCF for the 3 terms is 5p^3q

Factor the expression using the GCF

The translations for this problem are given, respectively, by:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For the first translation, the orientation remains the same, just the positions changes, hence it is translated 9 units to the right and 2 units down.

For the second translation, the rule applied to each vertex was:

(x,y) -> (x,-y).

Hence it was reflected across the x-axis.

For the third translation, the rule applied to each vertex was:

(x,y) -> (-x,y).

Hence it was reflected across the y-axis.

Based on the information illustrated,

the relation r on s is reflexive. Therefore, it's true.

If every component of a set X is related to one another, then a relation R over that set is said to be reflexive.

If (a, a) R for all  A, that is, if every element of A is R-related to itself, or if aRa for every a A, then R is set to be reflexive.

In the example question, S is the set of all Park students, and R is a relation over S.

When a relationship is described as xRy, it signifies that x and y have the same biological mother.

This relation is obviously a reflexive relation. xRx means x and x has the same biological mother. In this case, the relation satisfies the requirement for all aR (a,a) R.

Therefore, it's true.

The probability, P (yellow), that a yellow chip is drawn from the bag is 4/19.

Probability is a term used in mathematics to determine the likelihood that an incident will take place as in this case is the likelihood that a yellow chip is drawn from the bag.

Probability can be given by the formula:

probability= Number of favorable outcomes ÷ Total number of possible outcomes

Hence, in this problem, the formula for probability will be:

P (yellow) = Number of yellow chips / Total number of chips in the bag

The total number of chips in the bag will be equal to the sum of the chips of all colors.

That is, total number of chips = 3 blue chips + 7 red chips + 4 yellow chips + 5 green chips

Total number of chips = 19 chips

So the probability of a yellow chip being drawn out will be:

P ( yellow) = 4/19
