Question #7a695

Answer 1

The number `n` is `3.8`.

Explanation:

First, translate the English sentence to math. "Difference" means subtraction and "is" means equals. It will looks like this:

`stackrel(n-1.8) overbrace"The difference between a number n and 1.8"" " stackrel(=) overbrace"is"" " stackrel2 overbrace"2."`

Now solve for `n` in the equation:

`n-1.8=2`

Add `1.8` to both sides of the equation.

`n-1.8+1.8=2+1.8`

`ncolor(red)(cancel(color(black)(-1.8+1.8)))=2+1.8`

`n=2+1.8`

`n=3.8`

The number is `3.8`.
