Question

Use properties of operations to add (–3) and (–17). (1 point)

Answer 1

Use properties of operations to add (–3) and (–17).

Answer 2

To add \(-3\) and \(-17\), we can use the properties of operations, particularly the property of addition which states that adding two negative numbers results in a more negative number.

So, we can add \(-3\) and \(-17\):

\[
(-3) + (-17) = -(3 + 17)
\]

Now, we calculate \(3 + 17\):

\[
3 + 17 = 20
\]

Thus,

\[
(-3) + (-17) = -20
\]

Therefore, \((-3) + (-17) = -20\).

Answer 3

To add \(-3\) and \(-17\) using properties of operations, we follow these steps:

1. **Identify the Numbers**: We have two negative numbers, \(-3\) and \(-17\).

2. **Use the Property of Addition for Negatives**: The property of adding two negative numbers says that the sum is negative and equal to the sum of their absolute values.

3. **Calculate the Sum of Absolute Values**:
- The absolute value of \(-3\) is \(3\).
- The absolute value of \(-17\) is \(17\).
- Add these absolute values together: \(3 + 17 = 20\).

4. **Apply the Negative Sign**: Since both original numbers were negative, the sum will also be negative:
\[
(-3) + (-17) = -20
\]

Thus, the result of adding \(–3\) and \(–17\) is:

\[
\boxed{-20}
\]
