Well, honey, if you add 10, 20, and 30 together, you get 60. Then, to find the average, you divide that sum by the number of values, which in this case is 3. So, the average of 10, 20, and 30 is 20. And that's the tea, darling.

gcf(20, 30, 90) = 10
The answer is 10. 3 x 10 = 30 30 - 10 = 20
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.
10 - 2n = 30 10 - 2n + 10 = 30 + 10 2n = 40 2n/2 = 40/2 n = 20
5/10 = 1/2 write the proportion as ratios 5:10 = 1: 2 5/10 = 10/20 or 5:10 = 10:20 5/10 = 15/30 or 5:10 = 15:30
