What number produces an irrational number when added to 3/4

Anita began solving the system ​ {x+y=8, x−y=2 ​ by writing 2x=10 .

x+y=8

x−y=2

When we add both equations , we will get 2x = 10

x+x becomes 2x

+y -y becomes 0

8 + 2 becomes 10

So by adding two equations we got 2x = 10

Hence we say Addition Property of Equality.

Addition Property of Equality means adding both sides of equations.

x  terms  and y terms are added . then number are added on the right side

Answer:

Option C is correct

Addition property of Equality justifies the step.

Step-by-step explanation:

Given the system of equation:   x+y = 8  and x-y = 2.

Addition Property of Equality: The method of solving systems of linear equations is the addition Property, in which the two equations are added together to eliminate one of the variables.

Adding the equations states that we add the left sides of the two equations together, and we add the right sides together.

Using the addition property in equation: x+y=8 and x-y =2

then,

[tex](x+y)+(x-y)=8+2[/tex]  or

[tex](x+x)+(y-y)[/tex] =10

Eliminate the y- variable; we have

2x=10

Therefore, the only property justifies the step is, Addition Property of Equality.

By substituting y = 2x into the second equation and combining like terms, we get the equation 8x = 16.

This question is from the field of Algebra. You are asked to substitute the first equation into the second equation, then simplify by combining like terms. Substituting y = 2x from the first equation into the second equation 2x + 3y = 16, we replace y with 2x, thus transforming the second equation into 2x + 3(2x) = 16. Distributing the 3 to the 2x within the parentheses gives us 2x + 6x = 16. By combining the like terms on the left side, we get 8x = 16 which is option A.

Two decimals equivalent to 8.1 are 8.100 and 8.10. Zeroes added after the decimal do not change the value. 08.1 is also equivalent to 8.1 as a zero before the decimal does not alter the value.

Two decimals equivalent to 8.1 could be represented as 8.100 and 8.10. The reason for this is that adding zeros at the end of a decimal does not change its value. So, 8.100, 8.10, and 8.1 all represent the same decimal value.

Similarly, we can place a zero before the decimal, then 08.1 would be equivalent to 8.1. Note that the zero that comes before the decimal point does not change the actual value of the number.

Answer:

4.5 ÷ 3

Step-by-step explanation:

9/3 = 4.5

therefore this is the same as the previous expression

Final answer:

The expression 9/2 / 3 is equivalent to 9/2 * 1/3, which simplifies to 9/6 or 1.5. This multiplication by the reciprocal ensures the equality of the operation.

Explanation:

The expression 9/2 / 3 can be understood in terms of multiplication and division. When we divide by a number, it is the same as multiplying by its reciprocal. In this case, dividing by 3 is the same as multiplying by 1/3. Hence, we can rewrite the expression as 9/2 * 1/3.

To calculate this, we multiply the numerators together and the denominators together:

(9*1) / (2*3) = 9 / 6 = 1.5, or 3/2 when written as a fraction.

Performing the same operation on both sides of the equals sign maintains the equality. So, if any fraction has the same number in the numerator and the denominator, that fraction is equal to 1.

-3x + 2y + z = -6

(3)x + 3y + 2z = 5(3) We want to get rid of any variable within 2 equations. The easiest one would be by multiplying both sides of eq#2 by 3 and add it to eq#1.

-3x+2y+z=-6

3x+9y+6z=15

Add them together to get 11y+7z=9

(-4)x+3y+2z=5(-4) Now,multiply the original eq#2 by -4 to cancel out x in the last equation

-4x-12y-8z=-20

4x + 4y + 3z = 13

add them together to get -8y-5z=-7

Now multiply the eq 11y+7z=9 by 5 and the equation -8y-5z=-7 by 7 to cancel out the z variable when we add them together.

Once we multiply them, we get

-56y-35z=-49

55y+35z=45

add them together to get -y=-4 and we know y=4

substitute y into any equation here that has y and any other 1 variable like -8y-5z=-7 and get z=-5

Finally, we know y=4 and z=-5, we can substitue that into any of the original eqs like  -3x + 2y + z = -6 and we get x=-3

To check, just substitute these values into any of the equations above

An angle bisector divides an angle into two equal halves. The measure of angle AEC is: [tex]139^o[/tex]

Given that:

[tex]\angle AEB = 11x - 12[/tex]

[tex]\angle CED = 4x + 1[/tex]

Since ray BD bisects [tex]\angle BED[/tex], then:

[tex]\angle BEC = \angle CED[/tex]

This implies that:

[tex]\angle BEC = 4x + 1[/tex]

[tex]\angle AEC[/tex] is calculated as:

[tex]\angle AEC = \angle AEB + \angle BEC[/tex]

This gives:

[tex]\angle AEC = 11x - 12 + 4x + 1[/tex]

Collect like terms

[tex]\angle AEC = 11x + 4x- 12 + 1[/tex]

[tex]\angle AEC = 15x-11[/tex]

Next, we calculate the value of x as follows:

[tex]\angle AEB + \angle CED + \angle BEC = 180[/tex] --- angle on a straight line.

This gives:

[tex]11x - 12 + 4x + 1 + 4x + 1 = 180[/tex]

The term 'pageant' is most similar in meaning to 'show.' Both terms refer to public exhibits or performances intended to entertain.

The word pageant is conceptually closest in meaning to the term 'show.' A pageant typically refers to a public entertainment consisting of a procession of people in elaborate, colorful costumes, or an outdoor performance of a historical scene. This coincides with the term 'show,' which generally signifies a public display or exhibition, especially when intended to entertain. Drawing from the research conducted by anthropologist Marcia Ochoa, we commonly see pageants in the context of beauty competitions, such as Miss Venezuela, or similar contests held by specific communities, such as transformistas in Venezuela. These events focus on the public presentation of candidates, much like a show.

The word “pageant” is most similar in meaning to “show”.

The word “pageant” is derived from the Latin word "pagina," which means a play or stage. In modern usage, a pageant is a public entertainment consisting of a procession of people in elaborate, colorful costumes, or an outdoor performance of a historical scene. It’s essentially a type of show that is often grand and celebrates a special event or anniversary.

Beauty: This term often refers to a combination of qualities, such as shape, color, or form, that pleases the aesthetic senses, especially the sight. In the context of a beauty pageant, it’s a show that judges its contestants primarily on their physical appearance. However, the term “beauty” itself doesn’t convey the aspect of a show or performance that “pageant” does.

Sovereign: This term refers to a supreme ruler, especially a monarch. A sovereign might be a figure in a pageant, but the word “sovereign” itself refers to a position of power and rule, not a show or performance.

Gallant: This term is used to describe someone brave, heroic, or chivalrous. A person might behave gallantly in a pageant, but again, the word “gallant” itself doesn’t convey the meaning of a show or performance.

So, among the options provided, “pageant” is most similar in meaning to “show”, as both involve a public display or performance.

The initial number of transactions that took place in the first hour of Monday, which was 10, will not have any impact or bearing on the transactions for the rest of the day. Likewise, the initial number of transactions will not be affected by any other transactions or any other parameter. Thus, we can safely say that the initial number of transactions is neither an independent or a dependent variable.

Thus, out of the given options, Option C is the correct answer.

Yes, there is.

Two variable are in a proportional relationship if one is a multiple of other, i.e. if their ratio is constant.

In fact, two equivalent ways of saying that x and y are in a proportional relationship are saying that there exists a number k such that

[tex] y = kx\quad\text{or}\quad \dfrac{y}{x}=k [/tex]

In this case, you can see that the perimeter is always three times the side, which makes sense, because the perimeter of an equilateral triangle is composed of three "copies" of the side of the triangle.

So, the perimeter is a multiple of the side (with k=3), and in fact you have

[tex] p = 3s \iff \dfrac{p}{s} = 3 [/tex]

which are the two equivalent ways of saying that p and s are in a proportional relationship.

Yes, there is a proportional relationship between the perimeter and the side length of an equilateral triangle as indicated by the equation p = 3s. If you double the side length, the perimeter also doubles.

Yes, there is a proportional relationship between the perimeter and the side length of an equilateral triangle. This can be observed from the equation p = 3s, which indicates that the perimeter is always three times the length of each side. In terms of proportionality, if you double the side length of the triangle (for instance), the perimeter also doubles. This is because the three sides of an equilateral triangle are of equal length, so any change in side length will cause a proportional change in the perimeter.
