Answer 3

To evaluate the expression, substitute the given value of x into the expression:

x = -5/3

Now, evaluate the expression:

2/5 - 3/4 * |x + 1/3|

Substitute x = -5/3:

2/5 - 3/4 * |-5/3 + 1/3|

Now, perform the arithmetic operations inside the absolute value:

|-5/3 + 1/3| = |-4/3|

Remember that the absolute value of a negative number is its positive equivalent:

|-4/3| = 4/3

Now, substitute back into the original expression:

2/5 - 3/4 * (4/3)

Now, let's find a common denominator for 5 and 4:

The common denominator is 20:

2/5 = 8/20 3/4 = 15/20

Now, the expression becomes:

8/20 - 15/20 * (4/3)

Now, multiply the fractions:

8/20 - 60/60

Now, subtract the fractions:

(8 - 60)/60

-52/60

Finally, simplify the fraction:

-26/30

Both the numerator and denominator can be divided by 2:

-26/30 = -13/15

So, the value of the expression when x = -5/3 is -13/15.
