P and Q are two points on latitude 55°N and their longitude are 33°W and 20°E respectively. calculate the distance P and Q measured along a the parallel of latitude
b a great circle(π=22/7, R = 6,400km) ​

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 =
