Answer:
2
Step-by-step explanation:
2x – 3y + 5 – (x – 3y) = 11 – 2x . . . . . given
2x -3y +5 -x +3y = 11 -2x . . . . . . . . . . .eliminate parentheses
x +5 = 11 -2x . . . . . . . . . . . . . . . . . . . . . collect terms
3x = 6 . . . . . . . . . . . . . . . . . . . . . . . . . . add 2x-5
x = 2 . . . . . . . . divide by 3
The value of x is 2.
Answer:
The mean for the combined sample = 6.
Step-by-step explanation:
We have been given that one sample of n = 10 scores has a mean of M = 8.
So the sum of 10 scores for 1st sample will be: 
We are also told that second sample of n = 5 scores has a mean of M = 2.
So the sum of 5 scores for 2nd sample will be: 
When the both samples are combined, so total points will be: 
and total scores will be 
.
Therefore, the mean for the combined sample will be 6.

Answer:
Function
Step-by-step explanation:
Because there is an output for every input listed of its opposite.
There were 200 students that attend the dance.
<span>Actually the above equation can be solved by following the below steps to fins the value of x
Step1: 3(x-k)/w=4
Step 2: (3x-3k)/w=4
Step 3: (3x-3k)=4w
Step 4: 3x=4w+3k
So hence therefore by following the above steps we can conclude that the value of x is
Step 5: x=(4w+3k)/3</span>
