No. Taking any percent < 100% of a number will always be a smaller number, because you are finding a part of that number. (Percents > 100% are more than the number, and 100% is the number itself. 200%, for example, is twice the number.)

In a perfect number, the sum of all the factors (including the number itself) is twice the number. E.g., the sum of the factors of 6 is 1 + 2 + 3 + 6 = 12 (equal to 2 x 6). Every prime number has two factors: 1, and itself. So, the sum of the factors is only one more than the prime number itself; for any number greater than 1, this can't be twice the number. For example, the prime number 7 has the factors 1 and 7, which add up to 8.

2 x = 8 + 4x

It is: 3x = 2x+8 and the value of x is 8

If the unknown number is q then: 2q+25 = 72

2n + 4 = 25

Let this number be x, then 2x + 2 = x 2x - x + 2 - 2 = x - x - 2 x = -2 Thus this number is -2. Check: 2(-2) + 2 = -2? -4 + 2 = -2 ? -2 = -2 True

No. Since the square root of a number is whatever number times itself will equal the given number, there can be only one.

Five more than twice a number is -13 find the number

No. An exponent is the degree to which a number is multiplied by itself. For example in 23 the 3 is the exponent. 23 is equal to 2x2x2.
