In scienctific notation or in standard form 3,700 mile is expressed as
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.
We can solve this by setting up a proportion:
12 seeing the play/ 72 students = 210 seeing the play/ x students
We can cross multiply to solve for x:
(12)x=(72)(210)
12x=15,120
x=1,260 students who attend the school
X-3y=-5
-(x+3y=1)
-------------
-6y=-6
y=1
x=-2
