Hope uses the equation, 1 +1+y=4. to represent the situation.
What does the variable y represent in the equation?
Choose 1 answer:
Number of yo-yos Hope made
Number of meters of string in third yo-yo
Total number of meters of string Hope used

Answer 1

The variable Y represents the number of meters of string in the third yoyo

Explanation:

In this equation y stands for the unknown variable. The equation tell you that hope made 3 different yo-yos so the number of yo-yos hope made isn't unknown, meaning, it cant be the first answer. The problem also tells you that hope used a total of 4 meters of string which means that the total number of string used isn't the unknown variable. The number of meters of string in the third yo-yo is the only number that isn't. This makes the number of sting used in the third yo-yo the unknown variable, making it y.
