900. I noticed that if you divided 60 by two, and multiplied 15 by two, you would get 30 on both accounts. You could go even simplier and times 30 by 3, and divide 30 by three, which would make the equation 90x10. Soooo simple, but I knew that 3x3 equals 9, so I knew that the first part of the answer was 9, then I added the two left over noughts to the answer, which means I got 900. NOTE: The adding the zeros to the end of the answer ONLY works if both of the numbers you need to multiply have a zero in the one's column.

What is the LCM of 10 15 and 60?
If it cant be 60 then 120 is the lext least. 15 x 4 = 60 60 x 1 = 60 10 x 6 = 60 15 x 8 = 120 60 x 2 = 120 10 x 12 = 120

Two numbers whos product is -60 and sum is 11?
xy=-60 x+y=11 x=11-y (11-y)y=-60 x=11+4= 15 or x=11-15= -4 11y-y2+60=0 y= -4 or 15 so the answer is 15 and -4 or -4 and 15

What is the LCM of 10 15 and 60?
If it cant be 60 then 120 is the lext least. 15 x 4 = 60 60 x 1 = 60 10 x 6 = 60 15 x 8 = 120 60 x 2 = 120 10 x 12 = 120
X squared minus 19x plus 60?
x2 - 19x + 60 = x2 - 15x - 4x + 60 = x(x - 15) - 4(x - 15) = (x - 15)(x - 4)

What is fifteen plus x equals six x plus sixty?
x=-9 15 + x = 6x + 60 x = 6x + 45 -5x = 45 x = -9 15 + (-9) = (6 * (-9)) + 60 15 - 9 = -54 + 60 6 = 60 - 54 6 = 6 There is no answer because, 15+x=6x+60 -15 -15 x=6x+45 Which is imposible because "x" can't equal itself times six plus forty-five.
