This is because of points C, A, and B are all collinear, which means that they all fall on the same line. Since the points are collinear, the sum of CA and AB is the whole line, which is CB. I really hope this helps :)
<span>The sum of angles CAD and DAB is 180 degrees. This is because they are all on a straight line (because points CAB are colinear) and angles on a straight line add up to 180 degrees.</span>
The dependent variable is the cost of the jeans since it depends on how many jeans Ben bought. An equation that represents the situation is (4j - 12) + 7 = 92
$700.00 porque si cada uno recaudo por lo menos $25.00 entonces multiplicas 28 por los estudiantes y $25.00 por la cantidad menos recaudada equivalente a $700.00
