If the volume of a cube is 27 it means that one edge is equal to the cube root of 27
3*3*3=27
Edge=3

You will need to set up and solve 2 equations:
A) 3 Vans + 10 Buses = 379
B) 14Vans + 13 Buses = 624
Multiply equation A by -14
A) -42 Vans -140 Buses = -5,306 then Multiply equation B by 3
B) 42 Vans + 39 Buses = 1,872
Adding BOTH equations
-101 Buses = -3,434
Each Bus holds 34 Students
Putting this into equation A
A) 3 Vans + 10 Buses = 379
A) 3 Vans + 10 * 34 = 379
A) 3 Vans +340 = 379
A) 3 Vans = 39
Each van = 13 students
Answer: 0.039
Step-by-step explanation: you move the "3.9" 2 decimal places to the right. If you did the inverse (multiplying by 100) you would get 390.00
Y=-x+2
2y=x-8
these two lines both go through the point (4,-2)
solve: substitute the y in the second equation with (-x+2):
2(-x+2)=x-8
-2x+4=x-8
add 2x on both sides:
4=3x-8
add 8 on both sides: 12=3x
divide by 3 on both sides: x=4.
find y: y=-x+2=-4+2=-2
the solution is (4,-2)
18 times
Since there only two numbers greater than 4 (5 & 6), you subtract 2 from 6.
Then, you divide that from 72.
So, the number of times I would expect the outcome to be greater than 4 is 18.
