Question

John is four times as old as Ashley. If x represents Ashley's age, write an expression to represent how old John will be in 10 years.

Answer 1

`4x + 10`

Explanation:

Since John is four times as old as Ashley, and we represent Ashley's age with x, John's age can be expressed as 4x.

To find how old John will be in 10 years, simply add 10 to John's current age (4x):

`\textsf{John's age in 10 years} = 4x + 10`

So, the expression to represent how old John will be in 10 years is:

`\Large\boxed{\boxed{4x + 10}}`

Answer 2

4x + 10 years

Explanation:

If x represents Ashley's age, then John's age is 4x.

In 10 years, Ashley will be x + 10 years old.

John will be 4x + 10 years old in 10 years.

So the expression to represent how old John will be in 10 years is:

`\sf 4x + 10`
