This is how you solve it, and here is the answer!
Answer:
The answer is x=-17/3
Step-by-step explanation:
The Steps:
-8 + 5(1 + x) = 2x - 20
-8 + 5 + 5x = 2x - 20
-3 + 5x = 2x - 20
-3 + 3x = -20
3x = -17
x = -17/3
Answer: A

Answer:
y = $30x ;
1 : $30
Step-by-step explanation:
Given that :
$60 is saved in electricity bill for every 2 panels
Model, y
Amount saved, y = amount saved per panel * number of panels
Let number of panels = x
Hence, total amount saved, y ;
y = $30x
Ratio of panels to money saved :
Number of panels : amount of money saved
2 : $60
1 : $30
Hence, $30 is saved in cost of electricity bill per 1 solar panel purchased.
