The numbers are 4 and 14
The proper factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18. Their sum is: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 18 = 55. As their sum (55) is greater than 36, the number 36 is an abundant number.
Two factors of 56 with a sum of 18 are 8 and 10.
If the number is even and the sum of its digits is divisible by nine then the number is divisible by 18.
18
The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.
The numbers are 4 and 14
the sum of 18 and a number equals 24
18 + 4 = 22
Half of 18 is 9 and 5+4 = 9 so the number is 5
18 + n
6x + 18 = 4 - x 7x + 18 = 4 7x = -14 x = -2
18+10+4=32.
The sum is 32
The sum of the numbers 8, 6, and 4, is 8 + 6 + 4 = 18.
the sum of 8 and 4 times a number is 36
The proper factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18. Their sum is: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 18 = 55. As their sum (55) is greater than 36, the number 36 is an abundant number.
