# How do you translate the phrase into an algebraic: Fifteen less than twice Mary's points?

May 31, 2018

Using $x$ as the variable for mary's points...

$2 x - 15$

$2 x - 15$

#### Explanation:

The key realization here is that Mary's points are unknown, so we can represent it with the variable $x$.

Given that $x$=Mary's points, twice her points can be modeled as

$\textcolor{b l u e}{2 x}$

"Fifteen less" means we will be subtracting $15$ from the above quantity to get

$2 x - 15$

Hope this helps!
