What is the sum of an unknown number and three times the unknown number?
Four times the unknown number. Let's say the unknown number is x. x + 3x = 4x
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 does infinity times infinity equal?
infinity2 Well, your question does not specify whether the infinities are "countable" infinities (such as the number of integers) or "uncountable" infinities (such as the number of real numbers). If both multiplicands are countable infinities, the product is also countable infinity. If either multiplicand is uncountable, the product is uncountable infinity. Countable infinity is known as "Aleph null", and uncountable infinity as "Aleph one". Infinity times zero may possibly be equivalent to zero though ------------------------------------------------------------------------------------------- ∞ x ∞ = ∞ infinity times infinity equals to infinity Infinity is already the highest number. Technically speaking, there is no highest number. So infinity infinity's is infinity cause infinity is never ending.
Why is zero times infinity undefined?
Because zero multiplied by any number is always zero, but anything multiplied by infinity is infinity. Zero times infinity is being pulled both ways. Also, the definition of infinity is any number x divided by 0. When you multiply zero by infinity, the zeroes "cancel out", leaving absolutely nothing behind.
What is the number when 20 times the square of a non-zero number is equal to 20 times the number?
0
What is the sum of an unknown number and three times the unknown number?
Four times the unknown number. Let's say the unknown number is x. x + 3x = 4x
Does a negative number times positive infinity equal negative infinity?
Yes. Multiplying a negative number by a very large positive number will equal a large negative number. If you have the function y = -x, then as x approaches infinity, y will approach negative infinity at the same rate.
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.
Twice an unknown number?
twice an unknown number less one and one-half times the same number equals two ---- Let the unknown number be "x":: Equation: 2x - (3/2)x = 2

What is the number when 20 times the square of a non-zero number is equal to 20 times the number?
0
What is an expression for 20 times a number?
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
What number is more than infinity?
There is no number greater than infinity. Infinity is defined to be greater than any number, so there can not be two numbers, both infinity, that are different.However, when dealing with limits, one can approach a non-infinite value for a function involving infinity. Take, for example, 2x divided by x, when x is infinity. That value is indeterminate, because infinity divided by infinity is defined as indeterminate, and 2 times infinity is still infinity.But, if you look at the limit of 2x divided by x, as x approaches infinity, you do get a value, and that value is 2. This does not mean that 2x when x is infinity is twice infinity, it just means that, right before x becomes infinity, the ratio is right before 2.Infinity should not be thought of as a number, but rather as a direction. Whereas a number represents a specific quantity, infinity does not define given quantity. (If you started counting really fast for billions of years, you would never get to infinity.) There are, however, different "sizes of infinity." Aleph-null, for example, is the infinity that describes the size of the natural numbers (0,1,2,3,4....) The infinity that describes the size of the real numbers is much larger than aleph-null, for between any two natural numbers, there are infinite real numbers.Anyway, to improve upon the answer above, it is not meaningful to say "when x is infinity," because, as explained above, no number can "be" infinity. A number can approach infinity, that is to say, get larger and larger and larger, but it will never get there. Because infinity is not a number, there is no point in asking what number is more than infinity.
What is five times an unknown number decreased by the same unknown number is less than the opposite of the sum of the unknown and five?
Opposite of the sum is not a mathematical expression and I can only assume it means the difference.So,5x - x < |x - 5|Or 4x
What does b mean in c x 2 equals b?
An unknown number, we'll call it B, is the same number as an unknown number C times 2.
What is the domain of g of x is equal to negative 2 times x?
anything can be put into it so... (-infinity,infinity)
