Question

Is the following item an expression, equation, or inequality.

13 + 6
Inequality
Expression
Equatic

Answer 1

The item 13 + 6 is an expression because it does not contain an equal sign or inequality symbol, but rather it is a numerical expression representing a value.

Step-by-step explanation:

The item 13 + 6 does not include an equal sign, greater than, or less than signs, nor does it set the expression equal to anything. Therefore, it is not an equation or an inequality. Instead, it is an expression, specifically a numerical expression that represents a single value once evaluated. In mathematics, an expression can include numbers, variables, and operators, but it does not compare or equate to anything. Statement 11: Equations are just statements of truth that help us understand that an equation would need an equal sign, presenting a relationship of equality between two expressions. Without an equal sign or an inequality symbol like <, >, ≤, or ≥, the item cannot represent an equation or an inequality.

As an example of an inequality, if we had a statement like 13 + 6 > 15, this would be an inequality because it shows a relationship (greater than) between two expressions. To illustrate an equation, consider I₁ = 12 + 13 — this shows that two expressions are equal, meaning it is a statement of truth within the realms of mathematical laws, confirming 13 + 6 is simply an expression.

Answer 2

Expression

Step-by-step explanation:

An inequality includes variables and an equation includes an equal sign.

Hope this helps!
