The answer is 40.

50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260

10 + 10 + 10 + 10 = 40

40

30

10 + 30 = 40

209

10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150

I think you mean you want to pull the common factor(s) of 10 and 40 outside the expression 10 + 40. Since 40 is divisible by 10, 10 is clearly the gcf. So 10 + 40 = 10 * 1 + 10 * 4 =10 * (1 + 4).

40

50 - 40 = 10 + 0

18

50

23+7+10=40

The greatest common factor of 10, 18, and 40 is 2.

thinking is amazing

25 + 25

50

40+-30=10

10 + x = 50x = 40

4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2

Mean of 10 numbers is 58 so sum of 10 numbers is 580. One of them is 40 so the sum of the remaining nine is 540. So mean of the remaining nine is (their sum)/9 = 540/9 = 60 don't know if I'm understanding right but isn't it roughly 3.60
