89 - 21 = 68
The GCF of 18 and 21 is 3.The prime factorization of 18 is 2*3*3The prime factorization of 21 is 3*7So the GCF of 18 and 21 is 3.You can also notice that the difference between 21 and 18 is 3. The GCF can be no larger than the difference between the numbers. Since 3 is a factor of both 18 and 21, it is the GCF.The GCF is 3.3
2 and 3 are the first two prime numbers. The difference between them is 1
if you want to know more about the difference between 8997 and 9000 you must put this operation (9000-8997)=3 this
21, & 28. Because 7 x 3 = 21 7 x 4 = 28
NB 3,9,21,39,63. We note that #1;The difference between 3 & 9 = 6 #2 ;The difference between 9 & 21 = 12 ( 2 x 6) #3 ; The difference between 21 & 39 = 18 ( 3 x 6) #4 ; The difference between 39 & 63 = 24 ( 4 x 6) So it follows #5 ; The difference between 63 & X = ( 5 x 6 = 30 ) So 63 + 30 = 93 The answer !!!!!
24 + 21 = 45 24 - 21 = 3 Therefore, the two numbers are 21 and 24.
The product of 3 and 7 is found by multiplying the two numbers together, which equals 21. The sum of 3 and 7 is found by adding the two numbers together, which equals 10. Therefore, the difference between the product of 3 and 7 and the sum of 3 and 7 is 21 - 10 = 11.
89 - 21 = 68
24 and 21?
(X/3) - 11 =10 X/3 = 21 X = 63
It is 55 minus 21 = 34
21 is the answer
