Avan has room for six students and two teachers. how many vans are needed for a total of 48 students and 16 teachers

You would need 8 vans because:

48/6 = 8

16/2=8

Plus, if you add the number of students and teachers together it equals 64. Then divide it by the number of people who can fit into the van, which is 8.

64/8=8 vans

there will be needed 10 buses so other people can fit in

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
