1/4 is equal to 2/8.
2/8+1/8=3/8
Carla used 3/8 of the ribbon in all. So, 5/8 of the ribbon is left.
I hope this helps :)
Answer:
The slope is 
Step-by-step explanation:
∵ The rule of the slope passing through 2 points is:
m = 
∵ The points are (7 , 8) and (-7 , 1)
∴ m = 
Does this help it says the arc length is 12.56637
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
The slope of a line is given by:

We have that the line m passes through the following points:

So, the slope of the line m is:

Line n has the same slope so the equation is of the form:

We have as data that the y-intercept is
. Thus, we have that the equation of line n is:

ANswer:

((3-.5)/.5) x 100
that will give you your answer
