Mathematics: Finding the Sum of x and 10% of |x| with Calculation for x = -4

If x = -4, what is the sum of x and 10% of |x|?

To find the sum of x and 10% of |x| when x equals -4, we need to substitute -4 into the equation and then calculate the value

To find the sum of x and 10% of |x| when x equals -4, we need to substitute -4 into the equation and then calculate the value.

First, let’s find |x|, which represents the absolute value of x (the magnitude of x without considering its sign). In this case, |x| is the absolute value of -4, which is 4.

Next, we calculate 10% of |x|, which is 10% of 4. To calculate this, we multiply 4 by 0.1 (since 10% is equivalent to 0.1):

10% of 4 = 0.1 * 4 = 0.4

Now, we have found 10% of |x|, which is equal to 0.4.

Lastly, we need to find the sum of x and 10% of |x|. Substituting x = -4 and 10% of |x| = 0.4 into the equation:

Sum = x + 10% of |x|
= -4 + 0.4
= -3.6

Therefore, the sum of x and 10% of |x| when x equals -4 is -3.6.
