Answer: 5 multiples of 9
Step-by-step explanation:
First take the difference between 100 and 60.
100-60=40
Then divide the difference by 9.
40/9=4.44
4.44 rounded up is 5 ==> 5 multiples of 9
Primero toma la diferencia entre 100 y 60.
100-60=40
Luego divide la diferencia entre 9.
40/9=4,44
4.44 redondeado es 5 ==> 5 múltiplos de 9
Answer:

218 students - 20 students = 198 students on buses
198 students / 9 buses = 22 students per bus
Answer:
x= 9
y=-12.5
Step-by-step explanation:
3x+2y = 2×2
2x+2y =-7×3
6x+4y =4
- 6×+6y =-21
-2y =25
y=-12,5
2x+2(-12,5)= -7
2x+-25= -7
2x= -7+25
2x/2=18/2
x= 9
The mean is the average. If the mean of 4 letter (a,b,cd) is 12, the sum of them would be 12x4 =48
Now add e to the total: 48 + 50 = 98
The mean is the total divided by the quantity:
Mean = 98 /5 = 19.6
