How do you write the phrase into algebraic expressions: three more cookies than are in the jar?

1 Answer

Jul 18, 2016

$x + 3$ $x+3$

Explanation:

We don't know how many cookies are in the jar, so we can use a variable.

$There are$ $"There are"$ $x$ $x$ $cookies in the jar$ $"cookies in the jar"$

We are also told that there are 3 more cookies than there are in the jar, so we would just add $3$ $3$ .

$There are$ $"There are"$ $3$ $3$ $more than$ $"more than"$ $x$ $x$ $cookies in the jar$ $"cookies in the jar"$

Now to rewrite algebraically:

$x + 3$ $x + 3$
