Distribute...
99 - 9k = 9k - 27
Add 27 to both sides
126 - 9k = 9k
Add 9k to both sides
126 = 18k
Divide by 18
k = 126 / 18 = 7
A please? Jk but 3/20 and 3/10 and 9/20 have a pattern just make 3/10 6/20 by doubling it. She added 3/20 every time she ran again
Just keep going till you hit a hole fraction. By the 7th time she ran she ran 1 1/20 mile
<em>Answer:</em>
<em>(r + 9)(r - 3)</em>
<em>Step-by-step explanation:</em>
<em>r² + 6r - 27 =</em>
<em>= r² + 9r - 3r - 27</em>
<em>= r(r + 9) - 3(r + 9)</em>
<em>= (r + 9)(r - 3)</em>

Answer:
5y = x + 11
Step-by-step explanation:
Given parameters:
Equation of the line ;
y = -5x + 1
Coordinates = (2, -1)
Find the equation of a line perpendicular;
Solution:
A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.
Equation of a straight line is expressed as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
So, the slope of the new line perpendicular is
;
Now let us find the y-intercept of the new line;
x = -1 and y = 2
2 =
x (-1) + c
c = 2 +
=
The equation of the new line is;
y =
x +
or multiply through by 5;
5y = x + 11
