Answer:

37 boxes

Step-by-step explanation:

you should try and write each of the steps into an equation of x. Where x is the boxes she started with

so, she had x boxes, she bought 7 (that's addition) and then half of those boxes (that's division) got destroyed in the fire and she has 22 left (that's your total).

you can write the equation like this:

(x+7)/2 = 22

then, you solve

(x+7) = 44

x = 37

she originally had 37 boxes

58 boxes at first I got this by adding 22+7 which is 29 then multiplied two since it said half got destroyed and 29x2 is 58. So then I did 58/2 which us 29 minus the 7 she brought which is 22 and she has 22 left! I hope you understand lol

The center of a circle is 5 units below the origin, and the radius is 10 units. what is the equation of the circle?
levacccp [35]

Answer:

x² + (y + 5)² = 100

Step-by-step explanation:

If the center of the circle is 5 units below the origin, its x coordinate is 0 and its y-coordinate is -5. So, the center of the circle is at (0, -5).

Using the equation of a circle with center (h, k)

(x - h)² + (y - k)² = r² where r = radius of the circle.

Given that r = 10 units, and substituting the values of the other variables into the equation, we have

(x - h)² + (y - k)² = r²

(x - 0)² + (y - (-5))² = 10²

x² + (y + 5)² = 100

which is the equation of the circle.
