He is paid 4 per hour after school and 5 per hour on Saturday Last week he worked a total of 12 hours and made a total of 52.50 how many hours did he work on Saturday?
If X = hours worked after school If Y = hours worked Saturday X + Y = 12 4X + 5Y= 52.5 so we can re-arrange equation 1 to have X = 12 - Y if we substitute that into equation 2 4(12-Y) + 5Y = 52.5 48 - 4Y + 5Y = 52.5 Y= 4.5 and X = 7.5

How do you factor the trinomial 12x2 plus 16x-3?
12(x^2) + 16x - 3 *** notice no equal signs, the following is not equivalent to each other move coefficient x^2 + 16x - 36 (3 * 12) factor that (X + 18) (X - 2) re-put the 12 X+ 18/12 X - 2/12 simplify X + 3/2 x - 1/6 move denominator All that was just a math pattern, this is the actual factor: (2x+3)(6x-1) its kind of weird looking I know but if you re-multiply out you get: 12x^2 + 18x - 2x -3 VOILA!
