Answer:7300
Step-by-step explanation:
Answer:
600 miles in a day.
Step-by-step explanation:
Variable x = number of miles
Company A: 140 + 0.80x
Company B: 80 + 0.90x
Set up an equation:
140 + 0.80x = 80 + 0.90x
Isolate variable x:
60 + 0.80x = 0.90x
60 = 0.10x
600 = x
Check your work:
140 + 0.80(600) = 80 + 0.90(600)
140 + 480 = 80 + 540
620 = 620
Correct!
Step-by-step explanation:
Let a be the total score of Div. A
Let b be the total score of Div. B
given,

as equation 1.
and

as equation 2.
Now multiply equation 2 by 1/20 to eliminate b to solve for a.

take this new equation as equation 3.
now we will use equation 1 + equation 3 to eliminate b to solve for a.

Div.A total score = 600
Average Score = Total Score / Number of students.
