The two numbers are... -36 and -36
yes
They are 40 and 40
Ten and six.
64
-46
Two consecutive numbers which add up to 91 are the numbers one half either-side of 91/2 = 45.5. Therefore, the numbers are 45 + 46 = 91.
The numbers are 43, 44, 45, and 46.
No answer exists. Any 2 consecutive numbers will produce an odd sum.
To make the list of two-digit numbers with digits that add up to 10, first write the pairs of single-digit integers that add up to 10. They are (1,9), (2,8), (3,7), (4,6), (5,5). Then recognize that each of these pairs of numbers, except 5, can be combined in two different ways to make two-digit numbers that satisfy the problem. 19 and 91 28 and 82 37 and 73 46 and 64 55 So there are nine two-digit numbers with digits that add up to 10.
46 of them.
137 and 11 are two prime numbers that add up to 148.
4700
No two prime numbers can add to 119.
"Mean" without qualification usually refers to the aritmethic mean, also known as average. Add the numbers up, then divide by 4 (since there are two numbers).
The two square numbers that add up to 225 are 144+81 = 225
