Answer: There are 18 students in a van and 24 students in a bus.
Step-by-step explanation:
Let the number of students in the van be 'x' and the number of students in bus be 'y'.
Then, According to the question, we have the following system
![\text{[High School A ]}\ x+10y=258........................(1)\\\\\text{[High School B ]}\ 8x+5y=264........................................(2)\\](https://tex.z-dn.net/?f=%5Ctext%7B%5BHigh%20School%20A%20%5D%7D%5C%20x%2B10y%3D258........................%281%29%5C%5C%5C%5C%5Ctext%7B%5BHigh%20School%20B%20%5D%7D%5C%208x%2B5y%3D264........................................%282%29%5C%5C)
Multiply 2 to both the sides of equation (2), we get
Subtract equation (1) from equation (3), we get
Substitute value of x in (1), we get
Hence, there are 18 students in a van and 24 students in a bus.

The exponent tells you how many places to move the decimal. The positive/negative sign tells you which direction to move the decimal (negative is left, positive is right).
8.4 x 10⁻⁵ <em>move the decimal 5 places to the left</em> = 0.000084
