Question

A pine tree grows at a rate of 1.5 feet per year. James plants a 2-foot tall pine tree in his yard. How many years will it take for the tree to be at least 14 feet tall?

Answer 1

First, you would need to know the equation is 1.5x+2=14. Solving this would get you the answer. First, you subtract 2 from each side getting 1.5x=12. Then you have to divide both sides by 1.5 getting your answer x=8.

Answer 2

8 years. Beacuse 14-2=12 and then 12÷1.5=8.
