Answer 2

To evaluate the expression |1/5 - 3x| + 7(целых) 3/5 at x = 4/5, we substitute the value of x into the expression and perform the calculations.

Let's break down the expression step by step:

Step 1: Calculate the absolute value of (1/5 - 3x): |1/5 - 3x| = |1/5 - 3(4/5)| = |1/5 - 12/5| = |(-11/5)| = 11/5

Step 2: Multiply 7 by (целых) 3/5: 7(целых) 3/5 = 7 * (3/5) = 21/5

Step 3: Add the results from Step 1 and Step 2: |1/5 - 3x| + 7(целых) 3/5 = 11/5 + 21/5 = (11 + 21)/5 = 32/5

Therefore, when x = 4/5, the value of |1/5 - 3x| + 7(целых) 3/5 is 32/5.
