Suppose we have two urns labelledLandRfor left and right. Each urn contains 4 marblesgiving a total of 8 marbles. Four of the marbles are red, and four are green. LetX0be the numberof red marbles in UrnL. A person reaches with one hand into UrnLand the other hand into UrnR, selects a marble at random from each urn, and then switches those two marbles from one urn to theother (so each urn still has 4 marbles). LetX1denote the number of red marbles in urnLafter theswitch. Let

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
