The question is asking you to come up with a real-life example of something that can be represented as 15+ c= 17.50. If I were you I would do sales tax. You bought an item with a 15 dollar price tag, but when you go to check out 2.50 are added in tax to equal 17.50. to solve subtract 15 from 17.50: c= 2.50. Your variable (c) represents the sales tax. Hope that helps! :)

Answer:
The area increases by 5.46261%
Step-by-step explanation:
Well firstly, the area of an ellipse is not ab, but it's proportional to ab ( where a and b are the semi-minor and semi-major axes).
This tells us that when a increases by 2.74% and b increases by 2.65% the new area will be:
Answer:
there were 200 children and 500 adults at the show
Step-by-step explanation:
7x+10y=6400
x+y=700
x=700-y
7(700-y)+10y=6400
4900-7y+10y=6400
-7y+10y=1500
3y=1500
y=500
x=700-y
x=700-500
x=200
Answer:
1. x = 47
2. x = 156
3. x = 62
4. x = 58
Step-by-step explanation:
1. 180 - 133 = 47
2. 180 - 24 = 156
3. 28 + 90 = 118. 180 - 118 = 62
4. 32 + 90 = 122. 180 - 122 = 58
