The rule at Anna's house is that if she eats all of her vegetables and does all of her chores each day, she earns 2 hours of internet time which she can save. Anna started her week with 3 hours saved. If she eats all of her vegetables and does all of her chores each day for 4 days straight, how many hours does she have after the 4 days if she uses 6 hours of her internet time?

She has 6 hours left.

Step-by-step explanation:

She started with 3 hours saved and got 2 more hours for each day that she did her chores and ate her vegetables.  Since she did her chores and ate her vegetables 4 days that means that in total she gained 8 hours (4 * 2) plus the ones she already had saved.   So 8 + 3 = 12 - 6 = 6

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
