Answer: 7.5k
=========================================
We simply add up the three expressions
k+2.5k+4k = 1k+2.5k+4k = (1+2.5+4)k = 7.5k
Because we don't know the value of k, we leave it as is.
C - 1 1/4 > -2 1/2
c > 1 1/4 - 2 1/2
1 1/4 to improper fraction = (4*1 + 1)/4 = 5/4
2 1/2 to improper fraction = (2*2 + 1)/4 = 5/2
c > 1 1/4 - 2 1/2
c > 5/4 - 5/2 5/2 = (5*2)/(2*2) = 10/4
c > 5/4 - 10/4
c > (5 - 10)/4
c > -5/4
Hope this helps.

Radius of a Circle Given Center and Point</h2>
To find the radius of a circle when we're given the coordinates of its center and a point it contains, we can use the following formula for distance:
- is one point and is another
<h2>Solving the Question</h2>
We're given:
- Center: (-2,1)
- Point: (2,-1)
Plug these given points into the formula for distance:
<h2>Answer</h2>
Therefore, the radius of the circle is units, or approximately 4.47 units.
