8 - 3 2/5 =
explain how you got it, please, thank you

Step-by-step explanation:

First, we need to find a common denominator. In this question, we can write each number as a fraction since 8 = .  Therefore our new question is:

Now we can multiply both the numerator and denominator of  by 5 which gives us:

Next, we'll change to an improper fraction by multiply the whole number by the denominator and adding it to the numerator, (multiply 3 by 5, then add 2), which gives us .  

Finally, simply subtraction will give us the

If you want to convert the answer back into a mixed fraction, we can subtract the highest multiple of the denominator from the numerator without going over to get the numerator, and use that multiple as the whole number.  In this case, it would be 4 x 5 which is 20, and 23-20= 3.  

Therefore the answer is:

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.
