Simplify each inequality if needed. Then determine whether the statement is true or false. 2 • 5 ≥ 4 + 6

검증된 단계별 안내
1
First, simplify both sides of the inequality separately. On the left side, multiply 2 by 5 to get \(2 \times 5\).
On the right side, add 4 and 6 to get \(4 + 6\).
Rewrite the inequality with the simplified expressions: \(10 \geq 10\).
Interpret the inequality symbol \(\geq\), which means "greater than or equal to."
Determine if the statement \(10 \geq 10\) is true or false by checking if 10 is greater than or equal to 10.

Order of Operations

The order of operations dictates the sequence in which mathematical operations are performed, typically remembered by PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Applying this ensures expressions are simplified correctly before comparing values.
