Answer 2

To evaluate the expression 2/5 - 3/4 * (x + 1/3) when x = -5/3, follow these steps:

Step 1: Substitute the value of x into the expression. Step 2: Perform the operations in the parentheses. Step 3: Perform the multiplication and subtraction.

Let's go through the steps:

Step 1: Substitute x = -5/3 into the expression: 2/5 - 3/4 * (-5/3 + 1/3)

Step 2: Combine the fractions inside the parentheses: 2/5 - 3/4 * (-5/3 + 1/3) = 2/5 - 3/4 * (-4/3)

Step 3: Perform the multiplication and subtraction: 2/5 - 3/4 * (-4/3) = 2/5 - (-4/4) = 2/5 + 1 = 2/5 + 5/5 = (2 + 5)/5 = 7/5

Therefore, the value of the expression 2/5 - 3/4 * (x + 1/3) when x = -5/3 is 7/5.
