Step-by-step explanation:

Number of males in the meet were 8.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

Let the number of males be x.

∴ Number of females = x + 7

Total number of people attending meet = Number of male +

                                                                    Number of  females

23 = x + x + 7

23 = 2x + 7

16 = 2x

x = 8.

Thus number of males in the meet were 8.

Answer:

Step-by-step explanation:

Define two ways of painting to be in the same class  if one can be rotated to form the other.We can count the number of ways of painting for each specific class .

Case 1: Black-white color distribution is 0-6 (out of 6 total faces)

Trivially [tex]1^{2}[/tex]=1 way to paint the cubes.

Case 2: Black-white color distribution is 1-5

Trivially all [tex]\frac{6}{5}[/tex] =6 ways belong to the same class , so [tex]6^{2}[/tex] ways to paint the cubes.

Case 3: Black-white color distribution is 2-4

There are two classes for this case: the class  where the two red faces are touching and the other class where the two red faces are on opposite faces. There are 3 members of the latter class  since there are  3 unordered pairs of  2 opposite faces of a cube. Thus, there are [tex]\frac{6}{4}[/tex]-3=12  members of the former class . Thus, [tex]12^{2} + 3^{2}[/tex] ways to paint the cubes for this case.

Case 4: Black-white color distribution is 3-3

By simple intuition, there are also two classes  for this case, the  class where the three red faces meet at a single vertex, and the other class where the three red faces are in a "straight line" along the edges of the cube. Note that since there are 8 vertices in a cube, there are 8  members of the former class and [tex]\frac{6}{3} -8=12[/tex] members of the latter class. Thus, [tex]12^{2} - 8^{2}[/tex]  ways to paint the cubes for this case.

Note that by symmetry (since we are only switching the colors), the number of ways to paint the cubes for black-white color distributions 4-2, 5-1, and 6-0 is 2-4, 1-5, and 0-6 (respectively).

Thus, our total answer is[tex]\frac{2*(6^{2} + 1^{2}+ 12^{2}+ 3^{2})+12^{2}+8^{2}}{2^{12} } =\frac{588}{4096} = \frac{147}{1024}[/tex]

The perimeter of polygon JKLM = 85 units

The perimeter of polygon EFGH = 34 units.

The perimeter of polygon JKLM = JK + KL + LM + JM

The perimeter of polygon EFGH = EF + FG + GH + EH

Find the missing lengths using the similarity theorem:

JK/EF = KL/FG = LM/GH = JM/EH

Plug in the values

20/8 = KL/11 = LM/3 = 30/EH

20/8 = KL/11

KL = (20 × 11)/8 = 27.5

20/8 = LM/3

LM = (20 × 3)/8

LM = 7.5

20/8 = 30/EH

EH = (30 × 8)/20

EH = 12

The perimeter of polygon JKLM = 20 + 27.5 + 7.5 + 30 = 85 units

The perimeter of polygon EFGH = 8 + 11 + 3 + 12 = 34 units.

Considering the definition of an inequality and system of inequalities, the correct option is: "No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100."

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

A system of inequalities is made up of two or more inequalities.

The solution will be formed by the intersection of the half-planes of each of the inequalities, that is, it will be the enclosure that all the inequalities have in common. That is, the solution of the system is given by the region of the common plane of the half-planes that define each one of the inequalities.

In this case:

Answer:

x=5

Step-by-step explanation:

solution,

3x+7=22

or,3x=22-7

or,3x=15

or,x=15/3

:×=5

The value of x in the equation 3x + 7 = 22 is x = 5.

To find the value of x in the equation 3x + 7 = 22, we can solve for x as follows:

Subtract 7 from both sides of the equation:

3x + 7 - 7 = 22 - 7

3x = 15

Divide both sides of the equation by 3 to isolate x:

(3x)/3 = 15/3

x = 5

Therefore, the value of x in the equation 3x + 7 = 22 is x = 5.

A riddle is an intentionally framed ambiguous question or statement that requires ingenuity and critical thinking to solve or understand.

In the given riddle, all the two dogs, four horses, one giraffe and a duck are lying on the bed. Three chickens are flying over a chair.

Assumptions:

1) Bed is placed on the ground.

2) Bed and chair considered are of standard type.

case1:

If we consider the legs of only living organisms, the number of legs on the ground at the given instant will be 0.

case2:

If that's not the case, then a typical chair will have four legs, and a standard bed will also have four legs. So a total of 8 legs will be on the ground or floor of the room.

case3:

And if we consider the possibility of the chair being placed on the bed, then the legs of the chair will not touch the ground. So a total of 4 legs will be on the ground or floor of the room.

Area = 4x^2 + 13x - 12

Length = 4x - 3

The width is calculated using:

Width = Area/Length

This gives

Width = (4x^2 + 13x - 12)/(4x - 3)

Expand

Width = (4x^2 + 16x - 3x - 12)/(4x - 3)

Factorize

Width = (4x(x + 4) - 3(x + 4)/(4x - 3)

Factor out x + 4

Width = (4x - 3)(x + 4)/(4x - 3)
