Answer:
x = 40
Step-by-step explanation:
According to the Supplementary Angles Theorem, set <em>4x</em><em> </em><em>-</em><em> </em><em>20</em><em> </em>and <em>x</em><em> </em>equal to 180. Once done, combine like-terms to get <em>5x</em><em> </em><em>-</em><em> </em><em>20</em><em> </em><em>=</em><em> </em><em>180.</em><em> </em>So, straight off the bat, we know that <em>5x</em> has to equal 200 [bringing 20 over to the right side of the equivalence symbol], therefore 40 is equal to <em>x</em><em>.</em>

General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 4
y-intercept <em>b</em> = 12
<u>Step 2: Write function</u>
- Substitute [Form]: y = 4x + 12
Answer: 6
Step-by-step explanation:
3 times 2
The dimensions tell you that the pool is a rectangle and is going to have 2 sides equal to each other, and the other 2 sides equal to each other
-4
The slope of a parallel line will always be the same as the other lines slope.
