Answer:

6x + 19 + 3x + -6 + 5x + -15 = 180

19 + -6 + -15 + 6x + 3x + 5x = 180

19 + -6 = 13

13 + -15 + 6x + 3x + 5x = 180

13 + -15 = -2

-2 + 6x + 3x + 5x = 180

6x + 3x = 9x

-2 + 9x + 5x = 180

9x + 5x = 14x

-2 + 14x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 14x = 180 + 2

-2 + 2 = 0

0 + 14x = 180 + 2

14x = 180 + 2

180 + 2 = 182

14x = 182

Divide each side by '14'.

x = 13

6x+19+3x-6+5x-15=180

14x = 180 - 19 + 6 + 15

14x = 182

x = 182 : 14

x = 13

15 people shared 65 1/2 acres of land. How much did each get?

beks73 [17]

You need to divide 65 1/2 by 15.

$65 \dfrac{1}{2} \div 15 =$

$= \dfrac{131}{2} \div \dfrac{15}{1}$

$= \dfrac{131}{2} \times \dfrac{1}{15}$

$= \dfrac{131 \times 1}{2 \times 15}$

$= \dfrac{131}{30}$

$= 4 \dfrac{11}{30}$

Each one got $4 \dfrac{11}{30}$ acres.

Lots of red herrings in this question! The beacon is circular, so you need to find the area of a circle with a diameter of 36 inches.

Area of a circle = pi x radius^2

remember radius is half the diameter!
