Answer 3

To evaluate the expression (2/5x + 1/3) * (2 13/58), we'll simplify it step by step:

Step 1: Simplify the mixed number 2 13/58. To do this, we convert the mixed number into an improper fraction. 2 13/58 = (2 * 58 + 13) / 58 = 129/58

Now we can rewrite the expression as (2/5x + 1/3) * (129/58).

Step 2: Multiply the numerators and denominators separately. [(2/5x) * (129/58)] + [(1/3) * (129/58)]

Step 3: Simplify each fraction individually. (2 * 129) / (5x * 58) + (1 * 129) / (3 * 58)

Step 4: Perform the multiplications. (258) / (290x) + (129) / (174)

Step 5: Find a common denominator for the two fractions. The common denominator is the least common multiple of 290x and 174, which is 290x.

Step 6: Rewrite each fraction with the common denominator. [(258 * (174)) / (290x * (174))] + [(129 * (290x)) / (174 * (290x))]

Step 7: Simplify the numerators. (44932) / (50460x) + (37410x) / (50460x)

Step 8: Combine the fractions over the common denominator. (44932 + 37410x) / (50460x)

Now the expression (2/5x + 1/3) * (2 13/58) simplifies to (44932 + 37410x) / (50460x).
