Final answer:
The addition problems that will get the spider to -5 are -8 + 3, -10 + 5, 2 + -7, -4 + -1, and 10 + -15.
Step-by-step explanation:
In order to determine which addition problems will result in the spider reaching -5, we need to find the sum of each problem and see if the sum is -5. Let's go through each problem one by one:
- -8 + 3 = -5: This addition problem will get the spider to -5.
- -2 + 3 = 1: This addition problem will not get the spider to -5.
- -8 + -3 = -11: This addition problem will not get the spider to -5.
- -10 + 5 = -5: This addition problem will get the spider to -5.
- 2 + -7 = -5: This addition problem will get the spider to -5.
- -4 + -1 = -5: This addition problem will get the spider to -5.
- -4 + 1 = -3: This addition problem will not get the spider to -5.
- 10 + -15 = -5: This addition problem will get the spider to -5.
- -9 + 5 = -4: This addition problem will not get the spider to -5.
- 1 + 4 = 5: This addition problem will not get the spider to -5.
Therefore, the addition problems that will get the spider to -5 are: -8 + 3, -10 + 5, 2 + -7, -4 + -1, and 10 + -15.
