Answer:
n=-5
Step-by-step explanation:
-4=2n+6
-10=2n
-5=n
n
-
4
=
3
+
6
n-4=3n+6
n−4=3n+6
Solve
1
Add
to both sides of the equation
−
n-4+{\color{#c92786}{4}}=3n+6+{\color{#c92786}{4}}
n−4+4=3n+6+4
2
Simplify
Subtract
3n
from both sides of the equation
5
Divide both sides of the equation by the same term

x=148
First, find the missing angle by subtracting 100+48 from 180 (all of the angles in a triangle add up to 180). Then, subtract that from 180 (the angles are a linear pair, so they are supplementry, so they add up to 180) x+32=180.
x=148.

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00
4 years = 3×365 days + 366 days = 1461 days
cost of electricity = 1461 days × $0.06/day = $87.66
lifetime cost = purchase price + electricity + repairs
= $202.00 + $87.66 + 2·$29
= $347.66
