The perimeter of an equilateral triangle is 83 inches. If the length of each side is (2x -3), find the value of x.

Minchanka [31]

Answer:

$x = 15 \frac{1}{3}$

Step-by-step explanation:

Equilateral triangles have 3 equal sides.

Thus, perimeter of triangle

= 3(2x -3)

= 3(2x) +3(-3) <em>(</em><em>expand</em><em>)</em>

= (6x -9) inches

Given that the perimeter is 83 inches,

6x -9= 83

6x= 83 +9 <em>(</em><em>+</em><em>9</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

6x= 92

$x = 15 \frac{1}{3}$
