Imagine you are creating a new number system that uses 12 as the base. how many digits would be in your system?

There would be 12 different digits.

The number of this always corresponds to the number in the base. Consider our current system which is base 10. We have 10 numbers we can use for digits (0-9).  So a base 12 system would have to have 12.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
