Answer:
nice work hope to see it once its finished!
Step-by-step explanation:
So our equation currently is ⇒ 
<u>Let's first move all the constant to one side and group 'like variables' together</u>:
<u>Now lets complete the square of both equations</u>
<u><em>Now we know the circle's general equation format is</em></u>:
⇒
- (h, k) ⇒ coordinate of the center of the circle
- r ⇒ length of radius of circle
<u>Thus the radius of the circle is 7</u>
<u></u>
Hope that helps!

There are 16 cups in 1 gallon so you would have to turn the denominator in the fraction into a 16 meaning you would multiply by 4 (because 4 goes into 16, 4 times). Your new fraction is 12/16. now you do 6 gallons*16 cups and you get 96 cups. Then you add the fraction onto 96 and you would be adding 12. Your final answer is 108 cups in 6 3/4 gallons
Answer:
18
Step-by-step explanation:
A two-digit number (xy) will have the value 10x+y. The sum of its digits is x+y.
You want ...
10x +y = 2(x +y)
1 ≤ x ≤ 9
0 ≤ y ≤ 9
The equation can be simplified to ...
8x = y
The only single-digit values for x and y that satisfy the requirements are ...
x = 1, y = 8
The two-digit number of interest is 18.
_____
<em>Check</em>
Its sum of digits is 1+8 = 9. 2×9 = 18.
_____
<em>Comment on the relationship in the problem</em>
Many of us learned our multiplication tables for 9s by remembering that the sum of digits of 9n was 9, and that the leading digit of the product was n-1.
