How do write 0.72 repeating as a fraction?
You need to call your number "x", then write the following two equations:(Equation 1) x = 0.727272... Multiplying by 100, you get: (Equation 2) 100x = 72.727272... If you subtract equation 1 from equation 2, and solve for "x", you will get the number as a fraction.
How do you write a equation for the opposite of a number is -9?
Call your number any variable, for example x. Then: "A number": x "The opposite of a number": -x "Is": the equal sign. "The opposite of a number is -9": -x = -9
What is 0.48 repeating as a fraction in simplest form?
Call your number "x". Write the following:x = 0.484848... 100x = 48.484848... Subtract the first equation from the second equation. This will give you "x" as a fraction. See if you can simplify it.
What is 0.54 (repeating) as a fraction in simplest form?
Here is how you solve this. You call your number "x", and write:x = 0.5454... 100x = 54.5454... Then you subtract the first equation from the second, and solve the resulting equation for "x". This will give you "x" as a fraction. Simplify as appropriate.
What is a linear equation that is not true for even one real number and therefor has no solution?
A linear equation in one variable. Case 1: A conditional equation: True only for a value of the variable. Ex. x + 2 = 3, True only when x is 1. Case 2: Identity Equation: Always true. Ex. x + 2 = x + 2, True for any value of x. Case 3: x + 1 = x + 5, False for any value of x. We call a solution any value of the variable that satisfies the equation, meaning if we replace the variable with that value, the equation becomes a true statement. Example: -2(x -3) = 8 - 2x -2x + 6 = 8 - 2x (add 2x and subtract 6 to both sides) 0 = 2 False. Since this equation, which is equivalent to the original equation, is false, then the original equation is also false. Meaning, there is no real number for x that could satisfy the equation. So there is no solution to the equation.
What do you call a number that stands alone in an equation?
In an equation, a number that stands alone is called a constant. It is a fixed value that does not change during the equation or its solution.
