The score of Raven is 9 points
<em><u>Solution:</u></em>
Let the point scored by bangal be"x"
Score of Raven = 40 points
Given that,
The ravens scored 13 more than three times number points that the bangals scored in their last game
Score of raven = 13 + 3(score of bangal)
40 = 13 + 3x
Solve the above equation for x
3x = 40 - 13
3x = 27
x = 9
Thus the score of Raven is 9 points
Answer:
x = 35
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- Definition of a Line: A line is 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
40° + (2x + 30)° + 40° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 2x + 110 = 180
- Subtract 110 on both sides: 2x = 70
- Divide 2 on both sides: x = 35
