Sum the number and divide the answer by the number of values that were added together.

Let x be a number. 16=(3+x)*4 16=12+4x 16-12=12+4x-12 4=4x 4/4=4x/4 1=x Therefore a number is 1.

A factor is a number which, when multiplied by another number makes a third number. The factors of 9 are 3 and 3. The factors of 12 are 2, 2 and 3. SO 3 is a common factor of 9 and 12.

Sum the number and divide the answer by the number of values that were added together.

4. Reverse the process to find the number: 7 is added to the product of 3 and a number to get 19. The last thing done is add 7; the reverse process of add is subtract, so subtract 7, leaving: The product of 3 and a number is 19 - 7 = 12. The reverse process to multiply (product) by 3 is divide, so divide by 3, leaving: a number is 12 ÷ 3 = 4

Let x be a number. 16=(3+x)*4 16=12+4x 16-12=12+4x-12 4=4x 4/4=4x/4 1=x Therefore a number is 1.

Here it is how I did it: First of all I took that 75% is 3/4 of hundred, and then everything easy 3/4x + 6=x + 3 both sides multiply by 4 3x + 24= 4x + 12 24-12=4x-3x 12= x The number that you are looking for is 12

The number 2, in base 4 arithmetic.

-9

Nope - 1038 is an even number and thus is divisible by 2. Its digits added together total 12 - which is divisible by 3... therefore the original number is also divisible by 3 !!
