Answer:
The variable Y represents the number of meters of string in the third yoyo
Step-by-step 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.

Step-by-step explanation:
perimeter is sum of all the sides
To
get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do
this, we will get 20.70, which means that 20.70 milliliters of alcohol were
used. On the other hand, we can get the milliliters of water used through two
ways: the first one is by simply subtracting 20.70 from 690, which will give us
the answer 669.30. Another would be by multiplying 690 by 0.97, which will also
yield the answer 669.30. The number of milliliters of water used was 669.30.
