Final answer:
The correct algebraic equation for the phrase 'the quotient of the sum of 6 and a number x, and 4' is (x + 6) / 4.
Step-by-step explanation:
The phrase 'the quotient of the sum of 6 and a number x, and 4' requires us to first find the sum of 6 and the number x. This sum is represented as (6 + x) or (x + 6). Since we are looking for the quotient of this sum and 4, we need to divide the entire sum by 4, which is represented in algebraic form as (x + 6) / 4. Therefore, the correct algebraic equation that models the given word phrase is option B) (x + 6) / 4.
