Indicate which property is illustrated in Step 1.
Step 1 7 + (1 + 9) + 0 = 7 + (9 + 1) + 0
Step 2 = (7 + 9) + (1 + 0)
Step 3 = (7 + 9) + 1
Step 4 = 16 + 1(2 points)

The property illustrated in Step 1 is the associative property of addition.
-14 - 8.9 + 12.8 + -12.8
The problem does not specify what to do with the numbers after adding them. Please provide additional instructions in order to determine the next step.
-14.6 - 8.9 + 12.8 + -12.8
To evaluate the expression -14.6 - 8.9 + 12.8 + -12.8, follow these steps:
-14.6 - 8.9 = -23.5
-23.5 + 12.8 = -10.7
-10.7 + -12.8 = -23.5
Therefore, the expression equals -23.5.
The property illustrated in Step 1 is the commutative property of addition.
In Step 1 of the given equation, the property that is illustrated is the associative property of addition.
To understand why, let's break down the equation:
7 + (1 + 9) + 0 = 7 + (9 + 1) + 0
The associative property of addition states that the grouping of numbers being added does not affect the sum. In this case, the numbers 7, 1, 9, and 0 are being added.
By rearranging the parentheses in Step 1, we are changing the grouping of the numbers being added, but the order itself does not affect the result. Therefore, the equation remains true.
This property can be applied to a variety of mathematical operations, including addition and multiplication. However, in this particular case, it specifically demonstrates the associative property of addition.
