Which variable expression represents the word phrase?
six decreased by the sum of a number and two.
A- (m + 2) - 6
B- 6 - (m - 2)
C- (m - 2) + 6
D- 6 - (m + 2)
And?
To determine which variable expression represents the word phrase "six decreased by the sum of a number and two," we need to break down the phrase into mathematical operations.
The phrase states "six decreased by the sum of a number and two." This means we need to start with the number six and subtract (decrease) the sum of a number and two.
Let's break it down step by step:
1. Start with the number six: 6.
2. "The sum of a number and two" can be represented as (m + 2), where "m" represents a number. This expression represents adding "m" and 2.
3. Now, we need to subtract the sum (m + 2) from six. The correct expression would be 6 - (m + 2).
So, the variable expression that represents the word phrase "six decreased by the sum of a number and two" is D- 6 - (m + 2).
