Question

43) A tree 13 feet high grows at the rate of3feet each year. How many years will it take for the tree to grow to a height of 28 feet?

Answer 1

Let x be the number of years it takes for the tree to grow to a height of 28 feet.

After x years, the height of the tree will be 13 + 3x.

Since the height of the tree is 28 feet, we set the two heights equal and solve for x:

28 = 13 + 3x

Subtract 13 from both sides:

15 = 3x

Divide both sides by 3:

5 = x

So, it will take 5 years for the tree to grow to a height of 28 feet.
