You are looking for a number, known as x. If you add 3 to it, it equals 99. x plus 3 equals 99.

x + 3 = 99

Now you need to subtract 3 from x, so x is by itself. To keep the equation balanced- and therefore correct- you need to subtract 3 from both sides.

x + 3 - 3 = 99 - 3

x = 96

And there you have it.

divisible by 2 means even number. so it can not be even number. divisible by 3 means add all the number and divide 3..number 99 is divisible by 3 we start 99+3=102 but it is even number..105,108,111,114,117,120. (108,114,120 are even number so they can not be answer) answers are 105, 111,117.

99 is odd and if you added one more it would be 3 digit.

add up all of the numbers together and if the sum is divisible by 3 then so is the original number.example:333+3=99/3=333/3=11JANE BROWN

99 is not a prime number because it has more factors than 1 and itself. The factors of 99 are 1, 3, 9, 11, 33, and 99.

A number whose proper factors add up to less than the number is called deficient. 99 is a deficient number because the sum of its proper factors (1, 3, 9, 11, and 33) is 57.

Its a Sequence when you add 1 more number onto the last number you added on for example 1 is the first number you would add 2 which would make 3 then you would add 3 which would make 6 then you add 4 which would make 10 and so on.

No. When adding the smallest 2 digit number (= 10) to the smallest 2 digit number (again, 10) the result is a 2 digit number (10 + 10 = 20). When adding the largest 2 digit number (= 99) to the largest 2 digit number (again, 99) the result is a 3 digit number (99 + 99 = 198). As you can see, you'll either get a 2 or 3 digit number, but never a 4 digit number.

60 + (-57) = 3

the smallest number is 99. hope this helps

Little Mathematical trick. If the digits in a number add up to 3 or a multiple of 3 then that number is divisible by 3. If the digits of a number add up to 9 or a multiple of 9 then that number is divisible by 9. 2 + 9 + 7 = 18 ........which is a multiple of both 3 and 9. Lets start with 3 297 ÷ 3 = 99 (9 + 9 = 18 so we can divide again by 3 and/or9) 99 ÷ 3 = 33 (3 + 3 = 6 so we can divide by 3) 33 ÷ 3 = 11 (11 is a prime number so no more factors. The prime factors of 297 are 33 and 11. The factors of 297 are : 297, 99, 33, 27, 11, 9, 3 and 1
