Answer:
1 hundred and 3 tens
Step-by-step explanation:
I assume you mean 130 as hundreds and tens and the answer to that would be 1 hundred and 3 tens.
The answer is 2.2108
Solution:
first equation:
h = -0.2d² + 2.25d-d + 6h = 21.77
2nd equation:-d + 6h = 21.77d = 6h - 21.77
Then substitute:h = -0.2(6h - 21.77)² + 2.25(6h - 21.77)h = 3.9968
Answer:d = 2.2108
