The numbers are 28, 29 and 30.
28 +29 + 30 = 87
its 27 29 and 31
87,89,91.....87+89+91=267
To find the sum of the numbers between 43 and 87 inclusive, we need to add up all the numbers between them, including 43 and 87. There are a couple of ways to do this, but one common method is to use the formula for the sum of an arithmetic sequence: S = (n/2)(a + b) where S is the sum, n is the number of terms, a is the first term, and b is the last term. In this case, we want to find the sum of the numbers between 43 and 87, so: a = 43 b = 87 To find the number of terms, we need to count how many numbers are between 43 and 87, inclusive. There are 87 - 43 + 1 = 45 numbers. Therefore, the sum is: S = (45/2)(43 + 87) = 2025 So the sum of the numbers between 43 and 87 inclusive is 2025.

x - y = 17x + y = 87Add the two equations:2x = 104x = 52=================Subtract the first original equation from the second one:2y = 70y = 35
The numbers are 27, 29 and 31.
All prime numbers except for 2 are odd. The sum of any two odd numbers is even. Therefore, unless 85 is prime (it's not) or -2 is, (it's not) there aren't two prime numbers that will equal 87.
