Answer:
The age of the oldest brother must be greater than 21 years
Step-by-step explanation:
Let
x, x+1 and x+2 -----> the ages of the brothers
we know that
The sum of their ages must be greater than 60
so
The inequality that represent this situation is
[tex]x+(x+1)+(x+2) > 60[/tex]
Solve for x
Combine like terms
[tex]3x+3 > 60[/tex]
Subtract 3 both sides
[tex]3x > 60-3[/tex]
[tex]3x > 57[/tex]
Divide by 3 both sides
[tex]x > 19[/tex]
so
if [tex]x > 19[/tex]
[tex]x+1 >20\ years\\x+2 > 21\ years[/tex]
therefore
The age of the oldest brother must be greater than 21 years
Answer:
22
Step-by-step explanation:
It would be 22 since it says that there ages combined is greater than 60, not equal to 60.
21+20+19= 60, so the youngest age the oldest brother could be is 22 since
22+21+20= 63 which is greater than 60, not equal to 60.
