I asked two questions yesterday, and thankfully, bobpursley answered the latter. I accidentally typed in the first question wrong, so I'd really appreciate it if someone helps me out.
Thank you, and have a good day :)
1. Kevin is 3 years younger than Nora. If n represents Nora's age now, what was Kevin's age 4 years ago, in terms of n?
A. N + 7
B. N + 1
C. N - 1
D. N - 4
E. N - 7
If Nora is n years old NOW, then Kevin is NOW n-3
so 4 years ago Kevin was (n-3) - 4
= n - 7 , (E)
To solve this question, let's break it down step by step.
First, we need to understand the relationship between Kevin's and Nora's ages. The question tells us that Kevin is 3 years younger than Nora. We can represent Nora's age as "n."
Therefore, Kevin's age would be represented as "n - 3."
Now, the question asks for Kevin's age 4 years ago. To find that, we need to subtract 4 from "n - 3."
So, Kevin's age 4 years ago would be:
(n - 3) - 4
Simplifying this expression, we get:
n - 7
Therefore, the answer is E. Kevin's age 4 years ago, in terms of n, is N - 7.
