Why does a number with an exponet of 1 always ends up with the base number?
That is the law of exponents- the exponent is the number of times you multiply the number and times 1 5 to the third power is 5 x 5 x 5 x 1 = 125 5 to the second power is 5 x 5 x 1 = 25 5 to the one power is 5 x 1 = 5 = base number 5 to the zero power is 1
What number when increased by 1 and doubled and then increased by 5 has a result that is the same as when the number is increased by 1?
let x be the number, then: (x + 1) × 2 + 5 = x + 1 → 2x + 2 + 5 = x + 1 → 2x + 7 = x + 1 → 2x - x = 1 - 7 → x = -6 The number is -6. Checking: -6 +1 = -5; 5 × 2 = -10; -10 + 5 = -5 which is the same as -6 + 1 = -5.
5 times an unknown number decreased by the same unknown number is less than the opposite of the sum of the unknown number and 5. What is the number?
The answer is 1. 5 times x - x < 5 + x It has to be 1, anything over 1 could not be less than.
The square root of 5 less than 6 times a certain number is divided by the number and the quotient is 1. find the number?
Suppose the number is x then [6x - sqrt(5)]/x = 1 so 6x - sqrt(5) = x or 5x = sqrt(5) x = sqrt(5)/5 = sqrt(5)
Find the number of factors that the number 625 has?
Identify the prime factors of 625 which are : 5 x 5 x 5 x 5 = 625. The factors of 625 are therefore 1 x 625, 5 x 125 and 25 x 25. As the number 25 is effectively duplicated then 625 has 5 factors (1, 5, 25, 125 & 625)

A number with three or more factors?
There are an infinite number of them. Here are a few: 6 = 1 x 2 x 3 15 = 1 x 3 x 5 30 = 1 x 2 x 3 x 5 210 = 1 x 2 x 3 x 5 x 7 105 = 1 x 2 x 3 x 5 x 7 x (1/2) Any number with three or more factors is a composite number.
One number plus five times its reciprocal is equal to six what is the number?
Suppose the number is x. Then x + 5/x = 6 Multiplying throughout by x, x2+5 = 6x or x2 - 6x + 5 = 0 which can be factorised into (x-1)*(x-5)=0 So x = 1 (and 5 times its reciprocal is 5) or x = 5 (and 5 times its reciprocal is 1).
What is the next number in the pattern 1 8 27 64?
The next number in the pattern is 125.This pattern is determined by cubing the numbers.First number = 1 x 1 x 1 = 1Second number = 2 x 2 x 2 = 8Third number = 3 x 3 x 3 = 27Fourth number = 4 x 4 x 4 = 64Fifth number = 5 x 5 x 5 = 125etc.
5 times an unknown number decreased by the same unknown number is less than the opposite of the sum of the unknown number and 5. What is the number?
The answer is 1. 5 times x - x < 5 + x It has to be 1, anything over 1 could not be less than.
What is the reciprocal of 5 less than a number is 4 times the reciprocal of twice the number what's the number?
Suppose the number is x. Then 1/(x-5) = 4*(1/2x) Multiply both sides by x*(x-5) to give: x = 4*(x-5)/2 = 2*(x-5) = 2x - 10 and so x = 10
What number equals 25?
1 x 25, 5 x 5
How do you make a line plot?
First, you draw a horizontal line which is like your x-axis. Then, lets say your data ranges from 1-5, you number the line 1-5. Next, you put one x above each number for each time that number occurs.EXAMPLE: xx5 2 1 3 5 x x x x2 3 5 1 1 x x x x4 2 4 3 1 x x x x x2 3 5 1 1 x x x x x1 2 3 4 5
The square root of 5 less than 6 times a certain number is divided by the number and the quotient is 1. find the number?
Suppose the number is x then [6x - sqrt(5)]/x = 1 so 6x - sqrt(5) = x or 5x = sqrt(5) x = sqrt(5)/5 = sqrt(5)
Find the number of factors that the number 625 has?
Identify the prime factors of 625 which are : 5 x 5 x 5 x 5 = 625. The factors of 625 are therefore 1 x 625, 5 x 125 and 25 x 25. As the number 25 is effectively duplicated then 625 has 5 factors (1, 5, 25, 125 & 625)
What other number besides 1 can you multiply to get 5?
5
