Answer:
teds sister is 60 years old, ted is 120 some how, and joe is 123.
Step-by-step explanation:
half of a century is 50 because a century is 100 years and plus 10 years equals 60 and 60 times 60 equals 120 and 120 plus 3 years equals 123 so that's how I got the answers. At first this answer looks complicated you just have to read the question carefully.
Since anything multiplied by zero produces zero, we can say 0(a + 1) = 0 and (2a - 2)(0) = 0.
Thus, 2a - 2 = 0 or a + 1 = 0
2a = 2
a = 1
a = -1
We can conclude that a = 1 or - 1 will produce the end result as 0.
