Answer:
(16.5 + 1.5n)° = (12 + 2n)° [given]
=> 16.5 – 12 = 2n – 1.5n
=> 4.5 = 0.5n
=> n = 4.5/0.5
=> n = 9

Answer:
<h2>
<em><u>p = 35/9 = 3.889 </u></em></h2>
Step-by-step explanation:
The system has:
- No solutions for two parallel lines.
- 1 solution for two nonparallel lines.
- Infinite solutions for two equations that describe the same line.
<h3>How to identify the number of solutions for the systems?</h3>
A system of two linear equations is given by:
y = a*x + b
y = c*x + d
1) The system has no solutions when both lines are parallel lines, this happens when both lines have the same slope and different y-intercept.
y = a*x + b
y = a*x + d
2) The system has one solution when the lines have different slopes:
y = a*x + b
y = c*x + d
3) The system has infinite solutions when both equations describe the same line:
y = a*x + b
y = a*x + b
