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.
60 min in an hour right? 30 miles means 1 hr. 180/30 = 6. 6 is the number of hr it took to travel 180 miles. make sense?
It can be 8:12 or as a fraction it’s 8/12
Answer: -11
Step-by-step explanation:
For this problem, it is important to look at the domains next to the function. In this problem there is a function for when x < 1 and when x ≥ 1. 3 is greater than 1, so we will use the second equation.
From there, plug in 3 for x and solve.
-2x - 5
-2(3) - 5
-6 - 5
-11
