Answer 2

To evaluate the expression -3 + |x| when x = -5 2/3, first, we need to find the absolute value of x.

The absolute value of a number is the distance of that number from zero on the number line. It is always positive, so |-5 2/3| is equal to 5 2/3.

Now, we can substitute the value of |x| into the expression:

-3 + |x| = -3 + 5 2/3

Next, let's convert the mixed number 5 2/3 to an improper fraction:

5 2/3 = (3 * 5 + 2)/3 = (15 + 2)/3 = 17/3

Now we have:

-3 + 17/3

To perform addition with mixed numbers, we need to convert -3 into a fraction with the same denominator as 17/3, which is 3.

-3 = -3 * 3/3 = -9/3

Now the expression becomes:

-9/3 + 17/3

To add fractions, the denominators must be the same. As both fractions already have the same denominator (3), we can simply add the numerators:

(-9 + 17)/3 = 8/3

So, the value of the expression -3 + |x| when x = -5 2/3 is 8/3, which is also equivalent to 2 2/3.
