The two numbers that multiply to -15 and add up to 2 are 5 and -3. When you multiply 5 and -3, you get -15, and when you add them together, you get 2.
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.
The two numbers that add to -2 and multiply to -15 are 3 and -5. When you add them, 3 + (-5) equals -2, and when you multiply them, 3 × (-5) equals -15.
add to 15 and subtract to 7
The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.

13 and 2
To find the number that is in the exact middle of two numbers, add the numbers and divide by 2.25 + 15 = 40. 40 divided by 2 = 20.26.9 is one of infinitely many values between 27 and 15.
The two numbers are -2 and -15
Mode is the average. You have to add all the numbers together, and then divide by how many numbers there are. Example: Add: 1+2+3+3+6= 15 then Divide: 15/5=3. Three is your mode.
To find the mean, you add all of the numbers and divide by how many numbers you added together. 7+2+3+2+1=15. 15/5=3. The mean is 3.
Infinitely many. If you restrict yourself to positive numbers only, but allow repetitions, then there are 15. If you disallow repetitions, only 2.
