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.
The age of the oldest brother must be greater than 21 years
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
Solve for x
Combine like terms
Subtract 3 both sides
Divide by 3 both sides
if
therefore
20 degrees
9 - (-11) = 20 degrees
x + 8 = z
x + 8 - 8 = z - 8
x = z - 8
the rest is in a capture
