Last year, the tree in Pedro's front yard was 5.6 feet tall. This year, the tree is 2 feet less than the hight of Pedro's house. Pedro's house is 17 feet tall. How tall is the tree?

Respuesta :

It actually doesn't matter how tall is Pedro's try last year. This year it is 2 feet less than his house, which doesn't grow. 
17-2=15feet
the tree is 2 feet less than 17 feet, so the answer is 15 feet
