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

Downstream:
Upstream:
Sum means + difference is division
<span> x + y = 92 </span>
<span> x - y = 20
</span>
2x = 92 +20
<span>2x = 112 </span>
<span>x = 56 </span>
<span>x + y =92 </span>
<span>56 + y = 92 </span>
<span>y = 36
</span><span>'
answer 36 and 56</span>
Answer:
Yes, the graph makes it appear as if sales increased three folds.
Step-by-step explanation:
The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.
Last year sale was about 137000 and it grew to 150000 as a result of advertisement.
But from the bar chart, it seems there was three times increase in sales.
Answer:
Step-by-step explanation:
We are given with a
FILLED CIRCLE : If circle is filled that means that that point is also included in the number line solution.
here we are given that the arrow is pointing left from -2 and the circle is filled
hence -2 is included and as the arrow is pointing towards left towards negative , the includes all the point less or equal to -2
The solution of the in equation would be
x ≤ -2
Unfortunately none of the option gives the above value of x.
