Question

chose 2 numbers whose sum is -18
4.5
-22 1/4
-21
-20
5.5
-23 1/2
-24 3/4
-22 1/2
3
2
6.75
4.25

Answer 1

To find two numbers whose sum is -18, let's check some of the pairs from the provided list.

1. -22 1/4 = -22.25
2. -21
3. -20
4. -23 1/2 = -23.5
5. -24 3/4 = -24.75
6. -22 1/2 = -22.5

Now, let's look at some combinations:

1. -22.25 and 4.5:
\[
-22.25 + 4.5 = -17.75 \quad \text{(not a solution)}
\]

2. -21 and 3:
\[
-21 + 3 = -18 \quad \text{(solution found!)}
\]

3. -20 and 2:
\[
-20 + 2 = -18 \quad \text{(solution found!)}
\]

Thus, the pairs of numbers whose sum is -18 are:
- **(-21 and 3)**
- **(-20 and 2)**
