Question

Multiple Choice Question
Marco 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

The correct answer is:

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

In the equation \( 1.5x + 54 = h \), \( x \) is used to quantify how many years have passed since the tree was originally planted, affecting the growth calculation.
