Answer:

AC = 15 units

Step-by-step explanation:

Since BD is an angle bisector then it divides the opposite side into segments that are proportional to the other 2 sides, that is

$\frac{AB}{BC}$ = $\frac{AD}{DC}$ , substitute values

$\frac{12}{18}$ = $\frac{6}{x}$ ( cross- multiply )

12x = 108 ( divide both sides by 12 )

x = 9

Then

AC = 6 + 9 = 15 units

North Carolina has 12 less electoral votes than Florida. Write & solve a subtraction equation to find the number of electora

matrenka [14]

Answer: There are 27 votes for Florida.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of votes of North Carolina (15) must be equal to the number of votes of Florida (x) minus 12.

Mathematically speaking:

15 = x -12

Solving for x:

15+12 = x

27 = x

There are 27 votes for Florida.
