Answer:

#5/2bh - 10 #

Explanation:

If we break down each of the components of this, we can make it into an algebraic expression.

First, remember that the area of a triangle is #1/2bh#.

enter image source here

And they tell us to do #"5 times the area of a triangle"# so our equation will look like this so far:

#5(1/2bh) rarr 5/2bh#

The first part says "ten less than five times the area of a triangle", so we know that that part is going to be subtracted from the rest of the equation.

#5/2bh - 10 #

A couple things to remember that are helpful:

  1. "Less than" will always mean subtraction, whereas "more than" will always mean addition.

  2. Translate words into algebraic equations in small pieces and then combine them - it makes it easier to solve!
