The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is B. constant<\/strong>.<\/p>\n\n\n\n A constant refers to a value that remains unchanged throughout a given problem or equation. Unlike variables, which can take on different values, constants are fixed. Constants are essential in mathematical expressions, as they provide a stable reference point, allowing for comparisons, calculations, and problem-solving.<\/p>\n\n\n\n In mathematics, constants are typically represented by numbers or symbols that do not alter. For example, in the equation y = 3x + 7<\/strong>, the number 7<\/strong> is a constant because it does not change regardless of the value of x<\/strong>. Similarly, \u03c0<\/strong> (pi), which represents the ratio of a circle\u2019s circumference to its diameter, is another well-known constant, approximately equal to 3.14159.<\/p>\n\n\n\n On the other hand, a variable<\/strong> is a symbol used to represent an unknown or changeable value. In the equation y = 3x + 7<\/strong>, x<\/strong> and y<\/strong> are variables because their values can vary depending on the context. The variable x<\/strong> can take on different values, and as a result, y<\/strong> will change accordingly.<\/p>\n\n\n\n An algebraic expression<\/strong> refers to a mathematical phrase that can contain numbers, variables, and operators (such as +, \u2212, \u00d7, \u00f7). An example of an algebraic expression is 3x + 7<\/strong>, which combines a variable (x<\/strong>) and a constant (7<\/strong>).<\/p>\n\n\n\n An equation<\/strong> is a statement that two expressions are equal. For example, 3x + 7 = 10<\/strong> is an equation, where the two sides are equal when x = 1<\/strong>. The equation incorporates variables, constants, and operators to show the relationship between different quantities.<\/p>\n","protected":false},"excerpt":{"rendered":" It has a fixed value that does not change.
