Answer:
The length of the blue ribbon is approximately 8.333 inches
Step-by-step explanation:
The given information are as follows;
The given length of the red ribbon = 2 1/12 inches
The length of the blue ribbon is given as 4 × The length of the red ribbon
Therefore;
The length of the blue ribbon = 4 × 2 1/12 inches = 25/3 inches = 8 1/3 inches
The length of the blue ribbon = 8 1/3 inches ≈ 8.333 inches.

Answer:
Step-by-step explanation:
10 years ago, the sum of their ages was 65 -2·10 = 45.
If Karl was twice as old as Eddie, his contribution was 2/3 of the sum and Eddie's was 1/3. That is, Karl was (2/3)(45) = 30 and Eddie was 15 at that time.
Now, Karl is 40 and Eddie is 25.
__
This can be solved using a system of equations.
e = 65 -k
(k -10) = 2(e -10)
Substituting the first equation into the second gives ...
k -10 = 2((65 -k) -10)
k -10 = 110 -2k . . . . . . . simplify
3k = 120 . . . . . . . . . . . . add 10+2k
k = 40
e = 65 -40 = 25
