How do you get 17 with the numbers 1 2 3 and 4?
4 + 1 = 5 5 x 3 = 15 15 + 2 = 17
Can 2 go evenly into 15?
No, only these numbers can: 1, 3, 5, 15.
What is the greatest common factor of 12 15 and 30?
The factors of the numbers are 12: 1, 2, 3, 4, 6, and 12 15: 1, 3, 5, and 15 30: 1, 2, 3, 5, 6, 10, 15, and 30 The GCF of the three numbers is the largest number that is a factor of all three numbers, which is 3.
What is the mean for the numbers 1 2 3 4 and 5?
1+2+3+4+5=15/5=3
What is the sum of the first 5 numbers?
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
What is the mean of 7 2 3 2 1?
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.
How do you get 17 with the numbers 1 2 3 and 4?
4 + 1 = 5 5 x 3 = 15 15 + 2 = 17

What is the mean for the numbers 1 2 3 4 and 5?
1+2+3+4+5=15/5=3
What are two numbers that multiply to -15 and add to 19?
I'm sorry but there is no answer for that. here is why: if we formed this in an equation to find the answer - x^2+19x-15 then we try to factor AC= (-15) -15/1 = (15/1), (5/1), (3/1), (1), (-1), (-3/1), (-15/1) 15-1=-15* 15-1=14 -15+1=-14 3-5=-15* 3-5=-2 -3+5=2 none of these factors add up to 19 and so there is no rational numbers that multiply to -15 and add to 19
Which of these numbers is not a actor of 15 1 2 3 or 5?
2 is not a factor of 15, or any odd number.
What are the prime numbers from 1 to 15?
