9x+1 = 2x+15
Subtract 1 from both sides.
9x=2x+14
Subtract 2x from both sides.
7x=+14
Divide 7 on both sides.
x=2
Answer:
A. 12
Step-by-step explanation:
Selecting B, C, or D would create a difference of perfect squares since each of these numbers are perfect squares. Additional factoring would then be needed.

But selecting 12 gives
which cannot be factored. It is factored completely.
25 out of 65 people are wearing red, if there are 65 people at the party and only 25 are wearing red you would find the percentage by dividing 65 by 25 which equals to 2.6%
i hope this is correct im not great at math but i hope this helps
The distance formula is:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
To use it, you need to have two points on a line that will look like this:
(x1, y1) and (x2 , y2)
Then you just plug it in, and you get your answer.
X + 5x - 13 = 140
6x - 13 = 140
6x = 153
x = 25.5
5(25.5) -13 = 114.5
CHECK: 25.5 + 114.5 = 140
