Answer:
first is 3.5, second is 1
Step-by-step explanation:
-4.5 = x + 2x - 6
-4.5 - 6 = 3x
10.5 = 3x
10.5/3 = x
3.5 = x
2(3.5) - 6
7 - 6
1
To find mean/average it's fairly simple!! :)
The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52
Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)
51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)
-8 , 8 that’s the answer .jsjskkskskskkskskskksksks
From the given equation
105% * 90 = 200% * x
105/100 * 90 = 200/100 * x
105*90 = 200*x
x = 105*90/200
X = 21*9/4
X = 189/4
x = 47.25
Value of x = 47.25 or 47 1/4
