Solved Example

Q. Evaluate the expression for k=0.6k = -0.6.\newlineWrite your answer as a decimal or whole number.\newline89.1k=8 - 9.1k = _____
Solution:
  1. Substitute k=0.6k = -0.6: Substitute k=0.6k = -0.6 into the expression 89.1k8 − 9.1k.\newlineCalculation: 89.1(0.6)8 − 9.1(-0.6)
  2. Multiply 9.19.1 by 0.6-0.6: Multiply 9.19.1 by 0.6-0.6.\newlineCalculation: 9.1×0.6=5.469.1 \times -0.6 = -5.46
  3. Subtract result from 88: Subtract the result from Step 22 from 88.\newlineCalculation: 8(5.46)=8+5.46=13.468 - (-5.46) = 8 + 5.46 = 13.46
