Answer:
The number of blocks Serena walks from the school to the supermarket is x × 5 blocks
Step-by-step explanation:
The question asks the number of blocks Serena walks from the school to the supermarket
The location of Serena's school is on the 14th street and the location of the super market is on the 9th street, therefore the number of blocks Serena walks from her school to the super market is given as follows;
Number of street between Serena's school and the super market = 14 - 9 = 5 streets
Number of blocks street each street = x blocks
Number of blocks Serena walks = x × 5 blocks.
