Question

Ethan planted a tree that was 1.85 meters tall. Several years later the tree is 5.30 meters tall. Which equation can be used to find x, the number of meters the tree has grown?

Answer 1

5.30 = x + 1.85

x Equals The Difference

Answer 2

We know that:

• The tree was 1.85 meters tall.
• After several years, an unknown amount of years, the tree is 5.30 meters tall.

To show the meters the tree has grown, we just have to express:

Final highness = x + Initial highness; where x refers to the unknown meters that the tree has grown.

Now, we isolate x and solve:

5.30 = x + 1.85

5.30 - 1.85 = x

x = 3.45 m

Therefore, the tree has grown 3.45 meters. And equation that allow to find this result is 5.30 = x + 1.85.
