Q. Evaluate the expression for b=5.8b = 5.8.\newlineWrite your answer in simplest form.\newlineb−4−b+7=\frac{b - 4}{-b + 7} = __
  1. Substitute and Simplify: Substitute 5.85.8 for bb in the expression b−4−b+7\frac{b - 4}{-b + 7}.5.8−4−5.8+7\frac{5.8 - 4}{-5.8 + 7}
  2. Calculate Numerator: Calculate the numerator 5.8−45.8 - 4.\newline5.8−4=1.85.8 - 4 = 1.8
  3. Calculate Denominator: Calculate the denominator −5.8+7-5.8 + 7.\newline−5.8+7=1.2-5.8 + 7 = 1.2
  4. Final Division: Now we have 1.8/1.21.8/1.2.\newlineDivide both the numerator and the denominator by 1.21.2 to simplify.\newline1.8/1.2=1.51.8/1.2 = 1.5
