Answer 1

The verbal expression 'two times a number increased by seven' translates to the mathematical expression 2n + 7, which corresponds to option a.

Step-by-step explanation:

To translate the verbal expression 'two times a number increased by seven' into a mathematical expression, we need to identify the operations described by the words. The phrase 'two times a number' indicates multiplication, and 'increased by' indicates addition. If we let the variable 'n' represent the number, then the expression becomes 2n + 7, which means two times 'n' plus seven.

This expression corresponds to option a. The format of the expression aligns with basic algebraic principles of expressing multiplication followed by addition, where the multiplication is performed first due to the order of operations, and then the addition.
