Your answer would be the first on because when you set up your equation you can find 4 by dividing 42,980 by 10 4 times wich will give you 10^4 when you divide exponents you subtract so iwill look like this....
5x10^6
----------= 1.25x10^2
4x10^4
Answer:

Answer:
The number of students in each <u>van are 7</u> and number of students in each <u>bus are 23.</u>
Step-by-step explanation:
Let the number of students in each van be 'x' and number of students in each bus be 'y'.
Given:
<u>High School A:</u>
Number of students = 132
Number of buses = 3
Number of vans = 9
As per question,
-------1
<u>High School B:</u>
Number of students = 205
Number of buses = 8
Number of vans = 3
As per question,
-------2
Multiplying equation (2) by -3 and adding the result to equation (1), we get:


Now, plug in 23 for 'y' in equation (1) and solve for 'x'. This gives,

Therefore, the number of students in each van are 7 and number of students in each bus are 23
