<span>along with units digit being < tens digit....let see if we can come up with something. ones unit must be 0,2,4,6,or 8. if 0 then tens unit can be 1-9 case1 if 2 then tens unit can be 3-9 case2 if 4 then tens unit can be 5-9 case3 if 6 then tens unit can be 7-9 case4 if 8 then tens unit can be 9 case5 : 108 is covered in case1 because 0<8 :</span><span>case5: 98----9+8=17 to be divisible by 9 hunderds unit has to be 1 and 198 is not divisible by 12 : case4:96,86,76...96---9+6=16 to be div by 9 100's unit has to be 3 and that is more than 200. 86 ...8+6=14 to be div by 9 100's unit has to be 4....to big same problem with 76 : case3:94,84,74,64,54...9+4, 8+4,7+4,6+4,5+4 all present problems with #'s larger than 200 : case2:92,82,72,62,52,42,32 ...92,82,and 72 all get throw out because #'s larger than 200. 62 is 6+2=8..to be divisble by 9 100's unit must be 1...162..not divisible by 12 take 52,42,32 end up with being over 200 : case1:90,80,70,60,50,40,30,20,10... 90 larger than 200...80 is 8+0=8 in order to be divisible by 9 100's unit has to be 1. 180.......guess what this number is divisible by 9 and 12 and is less than 200 applying divisibility rules for the rest of the numbers in this case make all the numbers to large >200 : SO WE HAVE GONE THROUGH ALL THE CASES AND 180 is the only one that qualified there could be a simpler way but I will have to think on that</span>lets work backwards
On the set of axes below, graph the line whose equation is To graph your line, click to add your first point and then click again to add a second point. You can either undo or reset to redraw your line. LNE This linear equation contains the point State the value of .
First combine like terms (-9n-3n=-12n) Then, subtract 6n on both sides (to get rid of the 6n) = -18n Then, add 8 to both sides (does not matter) = 0 Finally divide (answer is 0)
