Evaluate each expression for p = -4, q = 8, and r = -10. See Example 6. (q + r)/ (q + p)

검증된 단계별 안내

Identify the given values: \(p = -4\), \(q = 8\), and \(r = -10\).

Rewrite the expression clearly. The problem states: \(q + r \quad q + p\). This likely means two separate expressions: \(q + r\) and \(q + p\).

Substitute the given values into the first expression: replace \(q\) with 8 and \(r\) with -10 in \(q + r\), so it becomes \(8 + (-10)\).

Substitute the given values into the second expression: replace \(q\) with 8 and \(p\) with -4 in \(q + p\), so it becomes \(8 + (-4)\).

Simplify each expression by performing the addition to find the numerical results for both \(q + r\) and \(q + p\).

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Substitution of Variables

Substitution involves replacing variables in an expression with given numerical values. This is essential for evaluating expressions like q + r or q + p by directly inserting the values of p, q, and r into the expression.

Order of Operations

The order of operations dictates the sequence in which parts of a mathematical expression are evaluated. Understanding this ensures correct evaluation of expressions, especially when multiple operations like addition and multiplication are involved.

Basic Arithmetic Operations

Basic arithmetic operations such as addition and multiplication are fundamental for simplifying expressions. Knowing how to correctly perform these operations with positive and negative numbers is crucial for accurate evaluation.
