4.
Alenkinab [10]

The statements with their relation to 0 are:

  1. Oliver owes his sister $27. \to -27
  2. A building is 38 feet tall. \to 27
  3. Erica jumped 2.7 feet above ground. \to 2.7
  4. The scuba diver was 38 feet below sea level. \to -38
  5. The basement is 8.3 feet below ground. \to -8.3

Statements that represent positions above the sea level are illustrated using the positive sign, while positions below the sea level are represented using the negative sign.

The above highlights imply that the following statements would be represented with positive sign:

  • A building is 38 feet tall.
  • Erica jumped 2.7 feet above ground.

This is so, because height and positions above the ground are above the sea level

Also, the following statements would be represented with negative sign:

  1. Oliver owes his sister $27. \to -27  
  2. The scuba diver was 38 feet below sea level. \to -38
  3. The basement is 8.3 feet below ground. \to -8.3

This is so, because debt and positions below the ground are below the sea level

State a conclusion that seems reasonable.
netineya [11]

Answer:

This is the identity property of addition which states that when you add zero to a number the results is the number itself.

Step-by-step explanation:

Hello,

Identity is a number<em> t</em> that when added to other numbers it gives the same number<em> t. </em>In mathematics, the additive identity is always 0. In this property a number is added to 0 where the sum is always the number. For example 0+ 96= 96.

Other properties in math that involve addition are the commutative property, associative property and the distributive property.

In the commutative property, when two numbers are added, the sum is the same regardless of the order of the addends. For example, 3+2=2+3

The associative property states that when three or more numbers are added, the sum is the same regardless of how the addends are grouped.For example (2+3)+4 = 2+(3+4)

The distributive property states that the sum of two numbers multiplied by a third number is equal to the sum of each addend multiplied by the third number. For example 2*(9+1)=2*9 +2*1.

Hope this Helps.
