Ava's Height = 
Olivia's Height = 
Lucas' Height = 

We know from the question that;



If Lucas is 1.78m tall, then he is 178cm tall, so 





We also know that;



As we have worked out that ,

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

55. i don’t no. but zhongshan
