Question

arco planted a tree that was 54 inches tall several years ago. The tree has grown at a rate of approximately 1.5 inches per year. Marco uses this equation to calculate the tree’s height,
1.5x + 54 = h
.


What does the x represent in this equation?

A.
The x represents the tree’s growth each year.

B.
The x represents the height of the tree today.

C.
The x represents the number of years since the tree was planted.

D.
The x represents the starting height of the tree.

Answer 1

In the equation \(1.5x + 54 = h\), the variable \(x\) represents the number of years since the tree was planted. Therefore, the correct answer is:

**C. The x represents the number of years since the tree was planted.**
