Question

Brad's scores on three math tests are three consecutive even integers. The sum of his test scores is represented by the expression below, where m represents his first test score.

Option 1: A: 7m
Option 2: B: 9m
Option 3: C: 3m + 6
Option 4: D: 7m + 6

Answer 1

The sum of three consecutive even integer test scores for Brad, with the first test score represented by 'm', is expressed by the equation 3m + 6.

Step-by-step explanation:

The subject of the question is Mathematics, specifically algebra, and it is aimed at Middle School students. The question involves finding an expression that represents the sum of three consecutive even integer test scores, given that m is the first score. The correct expression to represent this sum is Option 4: 3m + 6.

To explain why, consider that the first test score is m, being an even number. The second test score, as the next consecutive even integer, would be m + 2. The third test score would be m + 4. Summing these three scores gives us the expression m + (m + 2) + (m + 4) = 3m + 6, which is the sum of Brad's three consecutive even integer scores.
