x=3 1/4 is not a solution to the equation.
12 5/8=x+9 1/4 Subtract 9 1/4 from each side 3 3/8=x, but 3 1/4=3 2/8
So, if k/9=3/9, then k=3, because it is a variable substituting 3. :D Hope I could help!
<h3>Given ↓</h3>
- Two points that a line goes through
<h3>To Find ↓</h3>
<h3>Calculations ↓</h3>
When we have two points that a line passes through and asked to determine the slope of the line, the slope formula is going to come in handy.
This is the formula :

y2 and y1 are y-coordinates, and x2 and x1 are x coordinates
Plug in the values :


Which simplifies to
, or 1

There are a couple of equations u can use
x = original price
15% off the original price of the purchase :
x - 0.15x
OR
if u get 15% off, then u are paying for 85%
0.85x
Answer:
x = 16
Step-by-step explanation:
2(x - 1) - 6 = 24 ( add 6 to both sides )
2(x - 1) = 30 ( divide both sides by 2 )
x - 1 = 15 ( add 1 to both sides )
x = 16
