Evaluate P25 \frac{P}{2} - 5 when P=14 P=14

Full solution

Q. Evaluate P25 \frac{P}{2} - 5 when P=14 P=14
  1. Substitute pp value: Substitute the value of pp into the expression.\newlineWe are given p=14p = 14, so we substitute 1414 for pp in the expression P25\frac{P}{2} - 5.\newlineThis gives us 1425\frac{14}{2} - 5.
  2. Perform division: Perform the division in the expression.\newlineNow we divide 1414 by 22 to get 77.\newlineSo the expression becomes 757 - 5.
  3. Subtract to get final result: Subtract 55 from 77. Now we subtract 55 from 77 to get the final result. 757 - 5 equals 22.
