General Formulas and Concepts:
Pre-Algebra
- Order of Operations: BPEMDAS
- Equality Properties
Geometry
- All angles in a triangle add up to 180°
Explanation:
Step 1: Set up equation
(22x + 1)° + (6x - 17)° + (4x - 4)° = 180°
Step 2: Solve for x
- Combine like terms: 32x - 20 = 180
- Isolate x term: 32x = 200
- Isolate x: x = 25/4
