Answer:the equations are
x + y = 8
20x + 110y = 340
Step-by-step explanation:
Let x represent the number of commercials on which Alexa's songs were played.
Let y represent the number of movies on which Alexa's songs were played.
The total number of movies and commercials on which Alexa earned is 8. It means that
x + y = 8 - - - - - - - - - - - -1
Alexa will earn $20 every time one of her songs is played in a commercial and $110 every time one of her songs is played in a movie. Alexa earned a total of $340 in royalties. This means that
20x + 110y = 340 - - - - - - - - - - - -2
Answer:
2x + y = 3 becomes y = 3 - 2x
-2x + y = -1 becomes y = -1 + 2x
2x + y = 5 becomes y = 5 - 2x
Parallel: 2x + y = 5
Perpendicular: 0.5x + 7
neither parallel nor perpendicular to line a: -2x + y = -1
Eight hundred ninety four thousand, two hundred and seventeen. I hope this helps.

Solution: (-6,-4) for the graphed system( the point of intersection)
Note: when substituting -6 in for x in the original equation we see that it satisfies the equation. So -6 is the solution of the original equation.
Answer:
73 x 51 x 1/2(basically just dividing by 2) = 1861.5
1861.5 x 86(width) = 160,089 86 yd^3 is your answer.
