Lisa has three classes that each last 50 minutes. what is the total number of minutes of the three classes

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 =

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
