Well here is how you solve.
You first combine like-terms.
3x + 1 + 2x = 2 + 4x
5x + 1 = 2 + 4x
Then you isolate the variable by subtracting 1 from both sides.
5x = 1 + 4x
Then you do the same with 4x.
1x = 1
Now divide.
x = 1
Now I know this isn't the exact answer but if you look at the options you have, one of those shouldn't be shown, then that would be your answer. I hope this helps love! :)
For this, you have to calculate the Unit value,
Unit value of 1rst one, 4.99/6 = 0.83
Unit value of 2nd one, 7.99/10 = 0.79
As, 2nd one is cheaper, so it is better :))
Given:
15 students
2 students must be chosen.
No repetition, no order
This is a combinations problem. We use this formula: n! / (n-r)!(r!)
n = 15 ; r = 2
15! / (15-2)!(r!) ⇒ 15! / 13! * 2! = 105
Answer:
x=6
Step-by-step explanation:
22x-2=20x+10
22x-20x=10+2
2x=12
x=6
Answer:
(6) the letter n : intersection which means the number you will find at the first bracket and has the same number at the other bracket
