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.

( jake's age times 2 in order to represent being 2 years older, however... Mindy is 3 more years old than the product of that expression. This would add 3.)
</span>
So, C? m = 2j + 3
10.x=1
11.3/4y+4 , x=1/5y+1/5
12.x=2
