General Formulas and Concepts:

Pre-Alg

  • Order of Operations: BPEMDAS
  • Equality Properties

Geometry:

  • All angles in a triangle add up to 180°.

Step-by-step explanation:

Step 1: Set up equation

53 + 74 + (11x - 2) = 180

Step 2: Solve for x

  1. Combine like terms:                    125 + 11x = 180
  2. Subtract 125 on both sides:        11x = 55
  3. Divide both sides by 11:               x = 5

Answer:

x = 5

Step-by-step explanation:

All the angles of a triangle equal up to 180.

74+53 = 127

180 - 127 = 53

11(5) - 2 = 53

55 - 2 = 53

Hope this helps!
