Question

Hope made 3 3 different yo-yos. She used 1 3 4 1 4 3 ​ meters of string for the first yo-yo, 1 1 meter of string for the second yo-yo, and a total of 4 1 3 4 3 1 ​ meters of string. Hope uses the equation, 1 3 4 + 1 + y = 4 1 3 1 4 3 ​ +1+y=4 3 1 ​ to represent the situation. What does the variable y y represent in the equation?

Answer 2

The y variable represents the amount of string used for the 3rd yo-yo.

Explanation:

We have been given that Hope made 3 different yo-yos. She used
`1(3)/(4)` meters of string for the first yo-yo, 1 meter of string for the second yo-yo, and a total of
`4(1)/(3)` meters of string.

The equation
`1(3)/(4)+1+y=4(1)/(3)` represents the total amount of used string to make 3 yo-yo.

As Hope made 3 yo-yo and
`1(3)/(4)` represents string used for 1st yo-yo and 1 represents the string used for 2nd yo-yo.
`4(1)/(3)` represents total amount of string used to make 3 y-yo, therefore, y represents the amount of string used to make the 3rd yo-yo.
