5x - 4 = 26
What does x equal?
Answers
5x-4=26 <=> 5x=26+4
<=> x=30/5
<=> x=6
S={6}
Add 4 to both sides to get:
5x=30
Then divide both sides to isolate the variable:
x=6
so the answer is:
x=6
Hope this helps

The only part of this problem that's the least bit tricky is knowing
the formula for the volume of a sphere. Here is is:
Volume of a sphere = (4/3) (pi) (radius of the sphere)³ .
Everything else is just arithmetic.
pi . . . use 3.14
Radius . . . 2-1/8 inches. It'll be easier if we write that as 2.125 inches.
Now, just put the numbers into their places in the formula:
Volume = (4/3) (pi) (radius of the sphere)³
= (4/3) (3.14) (2.125)³
and run that through your calculator.
When I run it through mine, I get 40.174 in³ .
None of the choices is anywhere near that number.
I'm worried, and I don't understand that.
Maybe we should look back at the question, and notice that
it says "estimate" ... something you do quickly in your head.
OK. We know the real formula ... Volume = (4/3) (pi) (radius)³ .
How could we estimate this quickly in our head?
pi . . . instead of 3.14, just use 3
radius . . . instead of 2-1/8, just use 2 . Then (radius)³ = 2 x 2 x 2 = 8
Then (4/3) (pi) (radius)³ = (4/3) (3) (8) = (4/3) of 24 = 32 .
Well now, will you look at that ! I guess that's where the 32 came from
on the list of choices.

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)
Mean: The mean is the average of the numbers; a calculated (central) value of a set of numbers.
How to find it? We add all of the scores together and then divide them by the number of scores.
They gave us the numbers 20, 15, and 16
1st. Lets add
20 + 15 + 16 = 51
2nd. Divide by 3 since their are 3 test scores
51 ÷ 3 = 17
So rolanda's mean is 17!
They gave us the numbers 16, 19, and 17
1st. Lets add.
16 + 19 + 17 = 52
2nd. Divide by 3 since their are 3 test scores.
52 ÷ 3 = 17.333333333333333
So jetta's mean is 17.333333333333333
Now lets compare:)
Rolanda's mean = 17
Jetta's mean = 17.33333333333333333
Obviously, whos is bigger?
Jetta's Mean is bigger :)
Hope this helps!
