Question

A tree is 3 feet tall and grows 3 inches each day. Write an equation that represents how much the tree grows over time.

Answer 1

Your equation would look like this:
3+3x= t.
The 't' represents the tree, the '3x' is the 3 inches it grows each day and the '3' is the 3 feet you started with. The 'and' in your question represents add or '+' therefore, the equation is 3+3x= t.
Hope this helps!:)
