Determine which equation is false, based on the solution set S:{3}.

2t = 6
2(2c + 1) = 14
4m + 5 = 12
8 = 3p − 1

We're given : x+y+z = 4
x = -2y
z = -3y

So, we replace x = -2y and z = -3y in the original equation.

-> -2y + y + -3y = 4
-> -4y = 4
-> y = -1

Now we have the value of y, we substitute it into x and z
x = -2y = -2(-1) = 2
z = -3(-1) = 3

The value of the car in very nice condition is $5177.

From the information, a car that originally cost $3,668 in 1955 is valued today at $62,125 if in excellent condition, which is 12 times as much as a car in very nice condition.

Let the value of the nice condition car be x

Therefore, the expression will be;

= (12 × x) = 62125

12x = 62125

Divide

x = 62125 / 12

x = 5177

The value is $5177.

After calculating basic arithmetic we have come to find that, 1523 boxes of crayons are produced in each hour if crayons manufactory produces 36,552 crayons in an hour.

Arithmetic ((arithmós) 'number', 'art, craft') is a fundamental branch of mathematics that focuses on the properties of traditional operations on numbers such as addition, subtraction, multiplication, division, exponentiation, and root extraction.

Giuseppe Peano, an Italian mathematician, formalized arithmetic in the nineteenth century with his Peano axioms,[disputed - discuss], which are still very important in the field of mathematical logic today.

The prehistory of arithmetic is limited to a few artifacts that may indicate the concept of addition and subtraction, the best-known of which is the Ishango bone from central Africa, which dates from somewhere between 20,000 and 18,000 BC, though its interpretation is disputed.

We have given that

crayon manufactory produces 36,552 per hours

Each box contain 24 crayons

No. of boxes manufactured in 1 hour = 36,552/24

                                                              = 1523

Thus, 1523 boxes of crayons are produced in each hour if Crayons manufactory produces 36,552 crayons in an hour.

The numbers are 8, 9 and 0

Combination is the one of the method to show the number of arrangements the from collection of objects or numbers

Here we have to form 5 digits numbers using the digits 8,9 and 0

The ten thousand's place can be only filled with 8 or 9, we cant fill the digit 0 on the ten thousands place,

In remaining places we can fill all three digits

The graph of an inequality is a region in the Cartesian plane. To know which line is the limit of the graphical region, the inequalities are as if they were equations, that is, graph the following lines:

To do this, first clear y in each of the equations:

First equation

Second equation

Now, give x values ​​that are within the domain of each equation and replace them in each equation to find its corresponding value in y:

First equation

Second equation

Now, with the points found you can graph the lines that are the limit of the inequalities. So, you have

Finally, it only remains to paint the regions, taking into account the symbols of the inequalities

In the case of the first inequality, you can see that y "is less than" the rest of the terms, and in the second inequality, you can see that y "is greater than" the rest of the terms.

Therefore, the graph of the given system of inequalities is

The vertices of the image are the points J'(x, y) = (3, - 1), K'(x, y) = (4, - 5) and L'(x, y) = (0, - 3), respectively.

Triangles are created by three non-colinear points called vertices and the location of the image of the triangle is found by using a reflection around a line parallel to the x-axis for every point of the figure. This operation is described by the following expression:

P'(x, y) = P(x, y) - 2 · [P(x, y) - (p, k)]

Where:

If we know that J(x, y) = (3, - 5), K(x, y) = (4, - 1), L(x, y) = (0, - 3) and k = - 3, then the coordinates of the vertices of the image of the triangle are:

J'(x, y) = (3, - 5) - 2 · [(3, - 5) - (3, - 3)]

J'(x, y) = (3, - 5) - 2 · (0, - 2)

J'(x, y) = (3, - 5) + (0, 4)

J'(x, y) = (3, - 1)

K'(x, y) = (4, - 1) - 2 · [(4, - 1) - (4, - 3)]

K'(x, y) = (4, - 1) - 2 · (0, 2)

K'(x, y) = (4, - 1) + (0, - 4)

K'(x, y) = (4, - 5)

L'(x, y) = (0, - 3) - 2 · [(0, - 3) - (0, - 3)]

L'(x, y) = (0, - 3) - 2 · (0, 0)

L'(x, y) = (0, - 3) + (0, 0)

L'(x, y) = (0, - 3)

The vertices of the image of the triangle are J'(x, y) = (3, - 1), K'(x, y) = (4, - 5) and L'(x, y) = (0, - 3).

The equivalent expression of 8(x+3)−14(20x−56)​ is - 272x + 808.

Two algebraic expressions are equivalent, when the two expressions have the same value when we plug in the same value(s) for the variable(s).

In other words, two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same.

Therefore, the equivalent expression of 8(x+3)−14(20x−56)​ can be found as follows;

8(x+3) − 14(20x−56)​

open the parenthesis

8x + 24 -  280x + 784

combine the like terms

In elementary algebra, the binomial expansion defines the algebraic expansion of powers of a binomial. The binomial equation be 27x² - 300 exists 3(3x + 10)(3x - 10).

In elementary algebra, the binomial theorem (or binomial expansion) defines the algebraic expansion of powers of a binomial. According to the theorem, it exists possible to extend the polynomial  [tex]$(x+y)^n$[/tex] into a sum involving terms of the form [tex]$a x^b y^c$[/tex], where the exponents b and c exists nonnegative integers with b + c = n, and the coefficient a of each term exists a specific positive integer depending on n and b.

Let the binomial equation be 27x² - 300

Factor out common term 3:

[tex]$\quad 3\left(9 x^2-100\right)$[/tex] [tex]$=3\left(9 x^2-100\right)$[/tex]

simplifying the above equation, we get

Factor [tex]$9 x^2-100: (3 x+10)(3 x-10)$[/tex]

The area of a parallelogram is:

a = bh

The base, b, of the parallelogram is 14.

The issue with this particular figure? We need the perpendicular height. We are given the side width, but that cannot be used in the final equation. So, we employ the Pythagorean Theorem.

We know that in the right triangle, a = 4, and c = 8.

a^2 + b^2 = c^2
4^2 + b^2 = 8^2
16 + b^2 = 64
16 - 16 + b^2 = 64 - 16
b^2 = 48
√b^2 = √48
b ≈ 6.93

So, b in this right triangle is equal to h in the parallelogram. So:

a ≈ 14(6.93)
a ≈ 97.02

Cost of the TV before sale £350

We come across phrases like cost price, tagged price, discount, and selling price when making a purchase. Shop owners give discounts to customers to encourage product sales. Discount is the term used to describe a rebate or an offer made to clients on the listed price of goods. Let's examine the connections between these concepts.

Given,

Sale% = 20%

The cost of TV after the sale = £280

Finding the original price:

                   100% - 20% = 80%

So 80% is the price £280

We have to find the 20% which has been less

Or, £280 = 0.80 x T

Let the original price be T,

                               280 = 0.80 x T

                               280/0.80 = T

                                      350 = T

Hence, the original price of the TV was £350.

The running speed of Noah is 6 mph.

The formula for distance is given as:

D = v × t

Where D is the distance, v is the speed and t is the time.

Now,

When t = 1 hour,

D = 6 × 1 = 6 miles

When t = 1/2hour,

D = 6 × 1/2 = 3 miles

When t = [tex]1\frac{1}{3}[/tex] hour,

D = 6 × [tex]1\frac{1}{3}[/tex] = 6 × 4/3 = 8 miles

When t = [tex]1\frac{1}{2}[/tex] hour,
