Answer:

81+144i

Step-by-step explanation:

(-3\sqrt{-81})( -5+\sqrt{-9})+ 9i\\\text{Simplify the radicals}\\\sqrt{-81}=\sqrt{-1*81}=\sqrt{81}\cdot\sqrt{-1}=9i\\\sqrt{-9}=\sqrt{-1*9}=\sqrt9\cdot\sqrt{-1}=3i\\=(-3(9i))(-5+3i)+9i\\(-27i)(-5+3i)+9i\\\text{Distribute}\\=135i-81i^2+9i\\i^2=-1\\=135i+9i-81(-1)\\=81+144i

The residents of a city voted on weather to raise property taxes . THe ratio of yes votes was 3 to 5. If there were 4845 no vote
Basile [38]

The total number of votes would be: 7752 total votes.

Here's how you solve it!

For every 3 yes there was 5 no's.

You would but that into a fraction so it would be 3/5

Then you take the number of no votes and multiply.

3/5 x 4845

Then you would get 2907.

4845+ 2907= 7752

4845= no votes

2907= yes votes

7752= total votes

Hope this helps! :3
