Currently, I am $9$ times as old as my son. Next year, I will be $7$ times as old as my son. How old is my son now?

the correct answer is 45x

9×5=45 then add the x

207/8 is the right

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.
