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}

Whats the red angle?<br>i cant seem to understand anything
Harrizon [31]

Answer:

65°

Step-by-step explanation:

Sum of interior angles of a triangle = 180°

⇒ m∠EAB = 180 - 90 - 70 = 20°

⇒ m∠DAG = 90 - 45 - 20 = 25°

⇒ m∠AGD = 180 - 90 - 25 = 65°

ΔADG ≅ ΔAFG

⇒ m∠AGD = m∠AGF = 65°

ΔABE ≅ ΔAFE

⇒ m∠AEB = m∠AEF = 70°

A company sells a chair for $450. It costs them $350 to make each chair, plus fixed costs for operation of $20,000
lianna [129]

The cost and revenue function of the company are as follows;

  • cost function = 350x + 20000
  • revenue function = 100x - 20000

<h3>How to find the cost and revenue function?</h3>

It costs them $350 to make each chair, plus fixed costs for operation of $20,000. Therefore,

let

x = number of chair

cost function = 350x + 20000

The company sells a chair for $450. Therefore,

revenue function = 450x  - (350x + 20000)

revenue function = 450x - 350x - 20000

revenue function = 100x - 20000
