Tilly and Lilly worked together on a job. Tilley earned twice as much as Lilly, and together they earned $510. How much did each person earn?

Let x = Lilly's earnings

$510 = 3x. To find x, you have to divide both sides by 3.

$170 = x.

Tilly earned twice as much as Lilly so we multiply $170 by 2

$170 x 2 = $340

Lilly earned $170 and Tilly earned $340

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
