Jack and Jill both start at point A. They each walk in a straight line at an angle of 150° to each other. After an hour Jack has walked 4.5km and Jill has walked 6km. How far apart are they?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
