Question 467077
Let d = D's age in 2010
Let n = N's age in 2010
:
Write an equation for each statement
:Noel."
d = n + 6
:
"in the years 2000, Danny's age was 2 years more than 4 times the age of Noel in 1995."
d - 10 = 4(n-15) + 2
d - 10 = 4n - 60 + 2
d = 4n - 58 + 10
d = 4n - 48
Replace d with (n+6)
n + 6 = 4n - 48
6 + 48 = 4n - n
54 = 3n
n = {{{54/3}}}
n = 18 yrs old is Noel in 2010
:
:
Check solution in the statement; (d = 24)
"n the years 2000, Danny's age was 2 years more than 4 times the age of Noel in 1995."
24-10 = 4(18-15) + 2
14 = 4(3) + 2
