To find the unknown value in the equation \( 5.8 \times ??? = -26.97 \), we can isolate the unknown by dividing both sides of the equation by \( 5.8 \):
\[ ??? = \frac{-26.97}{5.8} \]
Now, we can perform the division:
\[ ??? \approx -4.65 \]
So,
\[ 5.8 \times -4.65 \approx -26.97 \]
The unknown value is approximately \( -4.65 \).
