ScanSolve AI Answer

Answer

-5∘C\text{-5}^\circ \text{C}

Step-by-step solution

3 steps

  1. Identify the starting temperature.

    The starting temperature is 4∘C4^\circ \text{C}.

  2. Determine the operation for "lower than".

    "Lower than" means to subtract. We need to subtract 9∘C9^\circ \text{C} from the starting temperature.

  3. Perform the subtraction.

    4∘C−9∘C4^\circ \text{C} - 9^\circ \text{C} 4−9=−54 - 9 = -5

    The temperature is -5∘C\text{-5}^\circ \text{C}.
