LCM(30, 40, 60) = 120 GCF(30, 40, 60) = 10

60 decreased by 40 is 20.

LCM(15, 20, 30) = 60

20

The LCM of 20 and 30 is 60. The multiples of 20 are 20, 40, 60, and so on. The multiples of 30 are 30, 60, and so on. So teh LCM of 20 and 30 is 60.

20+30+40+50+60+70+80 = 350Or (2+3+4+5+6+7+8)×10 = 350I'm not quite sure what 'pattern' means?

40 minutes 30 miles = 1 hour = 60 minutes 20 miles = 60 x 20/30 = 1200/30 = 40

20, 40, 60 and so on. 30, 60, 90 and so on. Common multiples include 60, 120, 180 and so on.

The multiples of 20 are: 20, 40, 60, 80, 100, 120, 140, etc ...The multiples of 30 are: 30, 60, 90, 120, 150, etc ...The multiples of 40 are: 40, 80, 120, 160, etc. ...The lowest multiple common to 20, 30, and 40 is 120, so the LCM = 120

it is 35

10, 20, 30, 40, 50, 60, and so on 10, 20, 30, 40, 50 The first ten multiples of ten are 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. 10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160,170,180,190.........................……and keep on adding 10.

it should be 30% because if you have 20% adenine, then that means you will have 20% thynine, therefore you have 40%. Now 100 minus 40 = 60. and since guanine and cytosine go together, they will have to be 30% each, since 30 +30 = 60 and 60 + 40 = 100 simple math. :)
