Answer:

the opposite number sentence is 10=7+3

The opposite number sentence 10 - 7 = 3 will be 10 = 3 + 7.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The sentence is given below.

10 - 7 = 3

Simplify the equation, then the equation can be written as,

10 - 7 = 3

10 = 3 + 7

The opposite number sentence 10 - 7 = 3 will be 10 = 3 + 7.

Answer: A rational number is any value that can be expressed as a ratio of two integers. An irrational number is any value that cannot be expressed as a ratio of two integers.

Rational 4 and 1/4

Irrational π and √3

If a number can be written in the form of the fraction of p and q then that number is known as the rational number whereas a number is not written in the form of the fraction p and q then that number is known as the irrational number.

Rational Number - If a number can be written in the form of the fraction of p and q then that number is known as the rational number, that is:

[tex]\rm Rational \;Number = \dfrac{p}{q}[/tex]

Where q is the denominator and p is the numerator.

For example -  [tex]\dfrac{4}{3}[/tex] , [tex]\dfrac{1}{4}[/tex] , etc

Irrational Number - If a number is not written in the form of the fraction p and q then that number is known as the irrational number, that is:

[tex]\rm Irrational \;Number \neq \dfrac{p}{q}[/tex]

Where p is the numerator and q is the denominator.

For example - [tex]\pi, \sqrt{3}[/tex], etc

Answer:

T'(2, - 5 )

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ), thus

T(- 2, 5 ) → T'(2, - 5 )

After a 180-degree rotation about the origin, the coordinates of point T' that is the image of T(-2,5) are (2,-5).

The coordinates of point T' after a rotation of 180 degrees about the origin are found by changing the signs of the original coordinates. The point T(-2,5) will thus be mapped to point T'(2,-5). This is because the 180-degree rotation reverses the direction of both the x and y coordinates. So, if the original point T has coordinates (x, y), then the rotated point T' will be (-x, -y).

Answer:

y = 3

Step-by-step explanation:

Given

3(2y + 5) = 33 ( divide both sides by the multiplier 3 )

2y + 5 = 11 ( subtract 5 from both sides )

2y = 6 ( divide both sides by 2 )

y = 3

Answer:

21 / 99

Step-by-step explanation:

You want to get rid of the decimals so

Let x = 0.21212121

then 100x = 21.21212121

then 100x - x = 21

99x = 21

x = 21 / 99

So 0.2121... is equal to 21 / 99

To write the repeating decimal 0.21212121... as a fraction, we can use the method of infinite geometric series. The fraction equivalent of the decimal is 21/99.

To write the repeating decimal 0.21212121... as a fraction, we can use the method of infinite geometric series. Let x = 0.21212121... . Multiplying both sides of the equation by 100 gives 100x = 21.21212121... . Subtracting the original equation from this, we get 99x = 21, which means x = 21/99. Therefore, the decimal 0.21212121... is equal to the fraction 21/99.

Answer:

Domain: {-3,-1,1}

Range: {-1,2,4,5}

The relation Q is described as a list of ordered pairs, shown below.

Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) }

Domain: {-2,-1,0,4}

Range: {-2,2,3,4}

Step-by-step explanation:

Because its the answer

The Domain: {-3,-1,1} and Range: {-1,2,4,5}

Domain – All of the values that go into a relation or a function are called the domain.

Range – All of the entities (output) which emerge from a relation or a function are called the range.

All input values that are used (independent values) forms the Domain set.

All output values that are used (dependent values) forms the Range set.

Example: Given Function:- f = 2x+1 , Find the domain, range if 1<=x<=5.

The values of x lies from 1 to 10.

So, domain is {1, 2, 3, 4, 5}.

The values of f obtained by putting domain elements in the function will be range.

So, range is {3,5,7,9,11}.

We have relation Q as

Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) }

so, we know domain are the input values

Domain: {-2,-1,0,4}

and range are the output values

Range: {-2,2,3,4}

The equivalent expression is: B. y = ((z + 4x)) / 7

To find an equation equivalent to 4x + 7y = z, we want to isolate one of the variables (either x or y on one side of the equation.

Let's isolate x in terms of y and z:

Starting with 4x + 7y = z, subtract 7y from both sides:

4x = z - 7y

Now, divide both sides by 4 to solve for x:

[tex]\[x = \frac{z - 7y}{4}\][/tex]

Therefore, the correct choice is option B: [tex]\(x = \frac{z - 7y}{4}\)[/tex].

Ah im too lazy to type out everything

The equation for the relationship between the number of pages left and number of hours is y = 555x - 555 * 444.

The relationship between the number of pages left to read (y) and the number of hours (x) can be represented by a linear equation.

Naoya reads at a rate of 555 pages per hour, which means he reads 555 pages in one hour. In 444 hours, he read 555 * 444 pages.

So, the equation for the relationship between the number of pages left and the number of hours is:

y = 555x - 555 * 444

In this equation:

- y represents the number of pages left to read.

- x represents the number of hours.

- 555x represents the number of pages he reads in x hours (555 pages per hour).

- 555 * 444 represents the total number of pages he read in 444 hours.

Hopefully it helps :D

In mathematical operations, the direction can be from left to right or right to left, but in general, operations are performed according to the BODMAS/PEDMAS rule, which directs us from left to right.

In mathematical operations, the direction can be either from left to right or right to left, this largely depends on the specific operation field. However, in general, mathematics operations follow the BODMAS/PEDMAS rule, and the operations are performed from left to right.

The rule simply states: Brackets, Orders (exponential, square roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right). If you have, for example, a problem like 3 + 4 * 2, you would first perform the multiplication (4*2 = 8), then add the answer to 3, for a total of 11.

Answer:

a. 276 vehicles

Step-by-step explanation:

7⁄10[13½] + 3⁄10[20] + 3v - 3 = [4][5280]

[tex] \frac{10323}{( \frac{7}{10})(13 \frac{1}{2}) + ( \frac{3}{10})(20) + 3} = v \\ \\ \frac{10323}{9 \frac{9}{20} + 6 + 3} = v \\ \\ \frac{10323}{9 \frac{9}{20} + 9} = v \\ \\ \frac{10323}{18 \frac{9}{20}} = v \\ \\ 559 \frac{21}{41} = v[/tex]

Now, we check to see which answer choice this quantity is closer to. Obviously, we will take 896 and 276:

-559 21⁄41 + 896 = 336 20⁄41

559 21⁄41 - 276 = 28221⁄41 → we take this number

* 559 21⁄41 is much more closer to 276 than it is to 896.
