"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409.

Answer:
15 5/9 °C
Step-by-step explanation:
Put 60 where F is in the equation and do the arithmetic.

... C = (135 +5)/9 = 15 5/9
 
        
             
        
        
        
Melissa tem 16 moedas
Juan tem o dobro, ou seja, 16 x 2 = 32
Na adição vai ser o mesmo resultado 
16+16=32
Se eles juntos tivessem 144 moedas.

144 ÷ 2 = ou seja dividido por duas pessoas sendo melissa e juan
R = juan tem 72 moedas.
Cada um vai ficar com 72 moedas
