How do you Use absolute value to write definition of the opposite of a nonzero rational number?
I would do it that way.
How can you write the expression a plus b plus a-b in equivalent form not involving absolute value.?
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
How do you write 50 as a proper fraction?
You cannot because 50 is an integer with an absolute value which is greater than 1. It is not a fraction.
How do you write an absolute value inequality for all numbers n that are within 5 units of 12?
well u do stuff to figure it out
What are some equivalent equations for -4 plus the absolute value of 5x equals 16?
You can add or subtract the same number to both sides of an equation without changing the solution, so adding 4 to both sides yields |5x| = 20. Since 5 is positive, it can be moved outside the absolute value: 5*|x| = 20. You can multiply or divide both sides of the equation by any non-zero number, so you can divide both sides by 5 to get |x| = 4.So x is either 4 or -4, will solve your equation. If you want to write the equation without using absolute value, you can write a quadratic equation which has solutions of 4 and -4: (x + 4)(x - 4) = 0 --> x² - 16 = 0
