Adam goes to a store an buys an item that costs x dollars. He has a coupon for 25% off, and then a 7% tax is added to the discounted price. Write an expression in terms
of x that represents the total amount that Adam paid at the register.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
