Question 1169117

Kevin is now four times as old as mark. Five years ago,
The sum of their ages was 45. How old are they now? (Hint:k=44)
<pre>Let Mark's age be M
Then Kevin's is: 4M
We then get: M + 4M - 2(5) = 45
5M = 55
Mark, or {{{highlight_green(matrix(1,6, M, "is:", 55/5, "=", 11, years-old))}}}
Now you can find Kevin's age!
