5x10 in expanded form is 500.
Answer:

Step-by-step explanation:
We have been given that Juan cuts a piece of rope that is 16 meter long into 2 equal pieces. We are asked to find the length of each shorter piece of rope.
To find length of each shorter piece of rope, we will divide total length of rope by 2 because Juan cuts the rope into two equal pieces.


Therefore, the length of each shorter piece of rope would be 8 inches.
