Maria uses 2 centimeters of tape for every present she wraps. Write an equation that shows the relationship between the number of presents x and the tape used y

y = 2x

Step-by-step explanation:

Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:

1 present wrapped - > 2 centimeters of tape

x presents wrapped - > y centimeters of tape

1/x = 2/y

x = y/2 - > y = 2x

From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.
