A. A(n) equation is a mathematical relationship that uses one or more variables, numbers, or operation symbols.

B. A(n) variable is a symbol that can be replaced by a number in a mathematical expression or equation.

C. A(n) equation is a mathematical sentence with an equal sign.

A. A(n) equation is a mathematical relationship that uses one or more variables, numbers, or operation symbols.

Example: The variable "x" is used in the equation 2x + 3 = 7. It demonstrates the relationship that arises when "x" is multiplied by 2, added to 3, and the result is 7 as the outcome.

B. A(n) variable is a symbol that can be replaced by a number in a mathematical expression or equation.

Example: In the equation 3y + 2 = 11, "Y" is the variable. The equation can be solved by changing the value of "y," which can take on a variety of possibilities.

C. A(n) equation is a mathematical sentence with an equal sign.

Example: 4 + 5 = 9 is an illustration of an equation. It states that combining 4 and 5 yields the number 9. The equal symbol denotes the equality or balance of the two sides of the equation.

Explanation:

A. An equation is a statement that demonstrates the relationship between different quantities, variables, or numbers using mathematical operations. It might have a variable or several that need to be figured out in order to arrive at a particular value or link.

B. A variable is a symbol that is used to signify an ambiguous or fluctuating quantity in mathematical statements or equations. It is made flexible and generic to represent different values or relationships inside the confines of a mathematical issue.

C. An equation is a mathematical statement that establishes the equality of two expressions by using the equal sign. It indicates that the values of the two sides of the equation are equal or the same. In order to show mathematical relationships and properties, equations are frequently utilised.

Answer:

xy = 42.6282051282...

Step-by-step explanation:

0.78x/7 = 19/4y

0.78x * 4y = 3.12xy

19 * 7 = 133

3.12xy = 133

3.12xy/3.12 = 133/3.12

Step-by-step explanation:

Value of x =  [tex]-2\frac{1}{4}[/tex]

Algebraic equation, statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root.

Examples: (y²x² + 2xy – y)/(x – 1) = 12.

Given, equation

[tex]\frac{4}{5}(x- \frac{3}{10} )[/tex] = [tex]-2\frac{1}{4}[/tex]

⇒4/5[(10x-3)/10] = -9/4

⇒2/5[(10x-3)/5] = -9/4

⇒(20x-6)/25 = -9/4

⇒80x - 24 = -225

⇒80x = -225 + 24

⇒x = -201/80

⇒x = -2.5125

⇒x = [tex]-2\frac{1}{4}[/tex]

Hence, the value of x in simplest mixed number is    [tex]-2\frac{1}{4}[/tex]

Answer:

b. LMN

Step-by-step explanation:

The angle opposite to the largest side is the largest angle, which means that angle MLN is the largest angle. Hence, option D is correct.

Two lines converge at a location, creating an angle. An "angle" is the term used to describe the length of the "opening" between these two rays. The letter is used to represent it. Angles are frequently expressed in degrees and radians, a unit of roundness or rotation.

The given lengths of the sides are,

LM = 13

MN = 17 and LN = 10

Then, the angle which is opposite to the side MN will have the greater angle then angle MLN has the greater angle.
