Answer:
x= 10/13
Step-by-step explanation:
First, we need to put the variable on one side and the constants on another side.
Also a positive and a negative equal a negative. [this is related to +(-8)]
10x+(-8)= -3x+2
+3x +3x
13x-8=2
+8 +8
13x=10
Finally you divide on both sides
13x/13=10/13
x= 10/13
I hope this is right! I tried my best
Answer:
The answer is B) 21, 34, 65

120 divided by 3 = 40.
In order to find the mean you must add up all of the numbers in the numerical data set, then divide that by how many numbers there are. Hope this helps! :)
Answer:
Solving the equation for all real solutions in simplest form.
we get 
Step-by-step explanation:
We need to solve the equation for all real solutions in simplest form.
First simplifying the equation:
Now, we can solve the equation using quadratic formula:
we have a = 1, b=-12 and c=12
Putting values in formula and finding values of x
So, we get value of z: z=10.9 or z=1.1
Solving the equation for all real solutions in simplest form.
we get
