We'll represent Louise's, Tammy's, Delores's, and Sheryl's point values with 
, 
, 
, and 
respectively since each one is 1 point more than the last.
Add all of these values up and set it all equal to 
.
Now, simplify.
Subtract 
on both sides.
Divide both sides by 
.
Since Louise's score is , the answer is 
.
<h3>Double-checking</h3>
To verify our answer, add the point totals , 
, 
, and 
.
This equals , so we can be sure the answer is correct.
Answer:
On the right is a circle with centre (0, 0), radius r and (x, y) any point on the circle. Distance between (0,0) and (x, y) equals the radius, r. If the centre is (0, 0), the equation of the circle will be of the form x2 + y2 = r2.
Since DE is the perpendicular bisector of JL.
The perpendicular bisector is a line that divides a line segment into two equal parts. It also makes a right angle with the line segment. Each point on the perpendicular bisector is the same distance from each of the endpoints of the original line segment.
Since, a perpendicular bisector is a line that divides a line segment into two equal parts.
So, JK=KL. (which is not given in the option)
Since ED is a perpendicular bisector. So, each point on ED is the same distance from the endpoints of line segment JL.
So, EJ=EL.
Therefore, Option 1 is the correct answer.
Answer: $22.50
Step-by-step explanation:
25% of 30 = 7.5
30 - 7.5 = 22.50
