The two numbers that are seven and five units away from zero on a number line are 7 and -7 for the seven units, and 5 and -5 for the five units. Therefore, the complete set of numbers is -7, -5, 5, and 7.

The volume of this cylinder is: 550 cubic units.
To find the number that is 8 units to the left of negative 7, you subtract 8 from negative 7. This calculation looks like: -7 - 8 = -15. Therefore, the number that is 8 units to the left of negative 7 is -15.
Hundreds Tens Units. 0 7 5So the 5 in 75 is 5 units, while the 7 is 7 tens.

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)
