Answer:
John's height = 130 cm
Alexa's height = 120 cm
Tacy's height = 100 cm
Step-by-step explanation:
We are given the falling in the question:
John's height = 130 cm
The total height of Tacy, John, and Alexa is 350 cm
Let x be Tacy's height and y be Alexa's height.
Thus, we can write the equation:
Tacy is 30 cm shorter than John.
Thus, Tacy's height =
Thus, Tacy is 100 cm tall.
Alexa is 20 cm taller than Tacy.
Thus, Alexa's height
Thus, the height are:
John's height = 130 cm
Alexa's height = 120 cm
Tacy's height = 100 cm
