This is the concept of arithmetic:
Given that Carol ran a total 1 3/4 miles for 5 days last week, the total distance covered was:
Total distance=(distance per day)×(total number of days)
=1 3/4×5
=7/4×5
=35/4
=8 3/4 miles
Total distance ran this week is:
Total distance=(2 1/4×4)
=9/4x4
=9 miles
therefore we conclude that the distance covered this week was greater than the distance covered last week.
b] this distance was greater by:
difference=(distance covered this week)-(distance covered last week)
=9-35/4
=(36-35)/4
=1/4
the answer is 1/4 miles

Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
The general form of an equation of a circle:
We have the center (-2, 1). Substitute to the equation in the standard form:
Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:
Therefore we have the equation:
Convert to the general form.
