If you mean 4-x = 18 then the value of x is -12 because 4--12 = 18
If you mean -x +x/3 = 12 then the value of x is -18 Check: --18 +(-18/3) = 12
2+5+9+12+18+18+20=8484 divided by 7 (the amount of numbers you added) equals 12so your answer is 12.
You need to be careful in how you write such questions as it is important to know if you mean: x - 12/2 = 18 or (x-12)/2 = 18 If x - 12/2 = 18 then x = 18 + 12/2 x = 18 + 6 x = 24 If (x-12)/2 = 18 then x - 12 = 18 * 2 x - 12 = 36 x = 36 + 12 x = 48
Mean (12, 18, 19, 20, 21) = 18
Mean= Sum of all terms/No.of terms Mean=18+4+24+18+13+18+12/7 Mean=107/7 Mean=15.2 Hence, the mean of the given equation is 15.2
The geometric mean of two numbers is the square root of their product. 18 x 8 = 144. The square root of 144 is 12. The geometric mean of 18 and 8 is 12.
The Geometric Mean of 12 and 27 is 18.0

If you mean 4-x = 18 then the value of x is -12 because 4--12 = 18
8+9+12+18+23/5=14
18 is.
If you mean -x +x/3 = 12 then the value of x is -18 Check: --18 +(-18/3) = 12
2+5+9+12+18+18+20=8484 divided by 7 (the amount of numbers you added) equals 12so your answer is 12.
You need to be careful in how you write such questions as it is important to know if you mean: x - 12/2 = 18 or (x-12)/2 = 18 If x - 12/2 = 18 then x = 18 + 12/2 x = 18 + 6 x = 24 If (x-12)/2 = 18 then x - 12 = 18 * 2 x - 12 = 36 x = 36 + 12 x = 48
