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

Minimum of 10 psi at idle, 20-30 at idle is average.Minimum of 10 psi at idle, 20-30 at idle is average.
A mean is an average An example 10 +20 +30 =60 The mean/average of this is 20
The average equals 30. So 10
You cannot. It should be their weighted average with the weights representing the number of observations in each average.For example, if 3 numbers have an average of 10 and 6 numbers have an average of 20, the combined average is not the average of 10 and 20 (which is 15).It is, in fact, (3*10 + 6*20)/(3 + 6) = (30+120)/9 = 150/9 = 16.66...You cannot.

30-20 = 10
30 or -10 if the 20 is negative.
