Let first number be x Let second number be y x = 7 * 1/2 y x * 2 = 7 * y 2x = 7y x : y = 7 : 2 (simplest form to fit previous line) 7 - 2 = 5 5 units = 35 1 unit = 7 2 units = 14 (answer for y) 7 units = 49 (answer for x)

They are -2 and 12.
Volume of a sphere in cubic units = 4/3piradius cubed
Subtracting a negative number is the same as adding a positive number. Also, adding a negative number is the same as subtracting a positive number. -7 + (-5) = -7 - 5 = -12 -7 - (-5) = -7 + 5 = -2
