Suppose 7 quarts of milk cost $5.25. Use the unit price (price per quart) to determine how much 2 gallons of milk cost?

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 =

1. evaluate 8x(2)y9(-2) for x=-1 and y=2 2. simplify the equation. -() 3. simplify the expression. [tex]\frac{5}{x(-2) y9(5)}[/tex]

Why is it so easy to buy on impulse and overspend with a credit card? what could you do to counteract this tendency?
