Answer:
x=+12
Step-by-step explanation:
4(x+6)=6x=16
We move all terms to the left:
4(x+6)-(6x)=0
We add all the numbers together, and all the variables
-6x+4(x+6)=0
We multiply parentheses
-6x+4x+24=0
We add all the numbers together, and all the variables
-2x+24=0
We move all terms containing x to the left, all other terms to the right
-2x=-24
x=-24/-2
Answer:

Answer:
The mean is 6.2.
Step-by-step explanation:
The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.
So:
Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31
You find the average by dividing the sum of the terms (31) by the number of terms (5).
31/5 = 6.2
The mean is 6.2.
I hope this helped! :)
Answer:
3/2
Step-by-step explanation:
A=a+b+c+d/4
subtract a from both sides
0=b+c+d/4
Subtract b from both sides
-b=c+d/4
Finally subtract d/4 from both sides
c=-d/4-b
