Each number is 4 times the previous number"
2*4 = 8
8*4 = 32
32*4 = 128
so next 3 are:
128 * 4 = 512
512*4 = 2048
2048 * 4 = 8192
512 , 2048, 8192
Step-by-step explanation:
y = kx, where k is a real constant.
When y = 12, x = 5.
=> (12) = (5)k, k = 2.4.
Therefore when y = 30,
x = y/k = (30)/(2.4) = 12.5.
The answer is 12.5.
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
