40:10=12:3
Solution:
Since
40 : 10 = 12 : X
Then we know
10/40 = X/12
Multiplying both sides by 12 cancels on the right
12 × (10/40) = (X/12) × 12
12 × (10/40) = X
Then solving for X
X = 12 × (10/40)
X = 3
Therefore
40 : 10 = 12 : 3

Answer:
Center: (1, 5)
Radius: r = 5
Step-by-step explanation:
Step 1: Rewrite equation
x² - 2x + y² - 10y = -1
Step 2: Complete the Square (x2)
x² - 2x + 1 + y² -10y + 25 = -1 + 1 + 25
(x - 1)² + (y - 5)² = 25
Step 3: Find answers
Center = (h, k)
(1, 5) as Center
Radius = <em>r</em>
r² = 25
r = 5
