Question

If Kate triples her height, she will be as tall as if she added 147.5 inches to half her height. How tall is Kate?

Answer 1

`"59 inches"`.

Explanation:

Let's call Kate's height `x`. We're going to set this up as an equation. Since three times her height is equal to `147.5` inches plus half her height, this can be written as:

`3x=147.5 + 0.5x`

Here `x` is her height in inches. By subtracting `0.5x` on both sides, we get:

`2.5x=147.5`

Divide both sides by `2.5`

`x=59`
