49 and 51 for example. Save 48; 52 47; 53 etc. Save
-4
5x - 4 = 47 Add '4' to both sides 5x - 4 + 4 = 47 + 4 5x = 51 Divide both sides by '5' 5x/5 = 51/5 x = 51/5 = 10 1/5 = 10.2
{x+y=51, x-y=26} x=38.5 y=12.5
The first fifty odd numbers are 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99.
47 is prime, the rest are composite.
A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In this case, the number 51 is a composite number because it has divisors other than 1 and itself, such as 3 and 17. Numbers 31, 41, and 61 are all prime numbers, as they only have two distinct positive divisors, 1 and the number itself.
47 is a prime number and is divisible by 1 and 47 only. 51 is divisible by 1, 3, 17, 51.
No
All the integers between the two.
No, 41, 51, 71, 81, and 91 are not prime numbers. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this case, all the numbers listed can be divided by numbers other than 1 and themselves, making them composite numbers.
48, 49 and 50 are all composite.
51 is composite.
29, 61, 23, 97, 41, and 67 are prime. 81, 51, 93, 77, and 39 are composite.
41, 43, 45... 46... 47, 49, 51
51 is composite.
Just 51
