The outside temperature dropped 23.4 °F from the time Taylor left for school to the time Taylor got home from school. It was 54.7 °F when Taylor got home from school. Write and solve an equation to find the outside temperature when Taylor left for school.

Aline on the wall and a line on the floor are skew. always, sometimes, or never?

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 =

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 20 = x a. 5, 4 b. -5, -4 c. -5, 4 d. 5, -4
