PLEASE HELP DUE SOON Find the length of the radius of each circle. To calculate the radius, divide the distance from the epicenter by 640 km.

Seismograph records were obtained from an earthquake in Central America. Using the information in the table, locate the epicenter on the map. You will need a compass and a ruler. On this map, 1 cm is equal to 640 km.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
