Dane is three years older than twice his brother's age,(b). Which algebraic expression below represents Dane's age?
A. b+3
B. 2b+3
C. 3-2b
D. 2b-3
Which do you think it is?
Hint
b = brother's age
2b = twice the brother's age
I think its c.
3yrs OLDER than his brother, so you would add + 3
B. 2b + 3
It is C
2 X (brother's age) + 3
To find the algebraic expression that represents Dane's age, we need to follow the information given in the sentence.
The sentence states that Dane is three years older than twice his brother's age. Let's break it down step by step:
1. First, we need to determine twice his brother's age. Twice his brother's age can be represented as 2b, where b represents his brother's age.
2. Then, we need to add three years to twice his brother's age to represent Dane being three years older. Adding three years can be expressed as +3.
Putting all this together, the algebraic expression that represents Dane's age is 2b + 3.
Therefore, the correct answer is option B: 2b + 3.
