Kwame’s uncle is seventeen less than three times Kwame’s age. Which of the equations represents Kwame’s uncle’s age (u) as it relates to Kwame’s age (k)?
A.
u=17-3k
B.
k=3u-17
C.
k=17-3u
D.
u=3k-17
The correct equation is:
D. u=3k−17u = 3k – 17u=3k−17
Explanation:
To find Kwame’s uncle’s age (u) in terms of Kwame’s age (k), the problem states that the uncle’s age is 17 years less than three times Kwame’s age.
This relationship can be expressed as:
- Three times Kwame’s age: 3k3k3k
- Subtract 17 years from this value: 3k−173k – 173k−17
So, the uncle’s age (u) is given by the equation:u=3k−17u = 3k – 17u=3k−17
Correct answer: D
