Both P waves and S waves travel outward in every direction from the site where the earthquake occurred. If Earth’s interior were entirely solid and uniform, how would an observer experience an earthquake that took place on the other side of Earth? Use the terms “P wave” and “S wave” in your answer.

To solve this system of equations by elimination, what operation could be used to eliminate the y-variable and find the value of x? 6x + 5y = 2 4x + 2y = 8 a) subtract 2 times the second equation from 3 times the first equation b) subtract 3 times the second equation from 2 times the first equation c) subtract 5 times the second equation from 2 times the first equation d) subtract 2 times the second equation from 5 times the first equation
