12.
R: 28 + 17
- Add the ones place: \( 8 + 7 = 15 \). Write down 5 and carry over 1.
- Add the tens place: \( 2 + 1 + 1 = 4 \).
- Result: \( 45 \).
Mapping Answers to Letters:
Now, we map the results to the corresponding letters based on the provided key at the bottom of the worksheet:
-
71 → T
-
62 → E
-
51 → A
-
54 → M
-
73 → W
-
56 → O
-
45 → R
-
80 → K
-
61 → F
-
41 → N
-
32 → U
-
90 → !
Decoding the Secret Message:
Using the letters from the solved problems, the sequence is:
-
T, E, A, M, W, O, R, K, F, N, U, !
The decoded message is:
"TEAMWORK!"
Final Answer:
\[
\boxed{TEAMWORK!}
\]
