Answer:
Van can carry 15 and bus 51 students
Explanation:
Let's mark the number of vans with x and number of buses with y.
That allows us to write equations:
1) 11x + 9y = 624 (high school A)
2) 5x + y = 126 (high school B)
This means that we have a system of the equations with two unknowns.
We can use x or y to solve this. Let's use x, but first we need to express y through x. We said that:
5x + y = 126
That means that:
y = 126 - 5x
Now, let's plug this in the equation 1):
11x + 9(126 -5x) = 624
11x + 1134 - 45x = 624
-34x = -510
34x = 510
x = 15
So, if x is 15, let's plug it in any of the two equations:
5x + y = 126
75 + y = 126
y = 51
So, a van carry 15 and a bus 51 students.
Information about polar bears is important for people to learn because polar bears are becoming extinct so it’s best to learn more about them, if more people know about them they’ll try to help them, besides they are also part of the food chain.
