Answer: 2 buses and 4 vans would be needed
Step-by-step explanation:
Let x represent the number of buses that would be needed.
Let y represent the number of vans that would be needed.
There will be six drivers, and two different types of vehicles. This means that
x + y = 6
142 students are going on a field trip. A bus can hold 51 people while a van can hold 10. This means that
51x + 10y = 142 - - - - - - - - - - - 1
Substituting x = 6 - y into equation 1, it becomes
51(6 - y) + 10y = 142
306 - 51y + 10y = 142
- 51y + 10y = 142 - 306
- 41y = - 164
y = - 164/ - 41
y = 4
x = 6 - y = 6 - 4
x = 2

Can you send me the another photo because it not understandable.
I will solve this. but question is also not completed.
Let n be the amount of points earned in round 5
the goal of the game is to get zero when you add up the point value from all the rounds.
this means
-9 +3 + (-8)+ 2 +n =0
add up all the given numbers, then see which number(n) is required in order to get zero
any questions?
