16*8=128 and 128*12= is 1,536
That's false.
Let's see an instance:
10% of 300=30
20% of 100=20
It doesn't work here so it's false
Answer:
p = 14
Step-by-step explanation:
18 = p + 4

Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind
16 - 12 =4
36 - 27 = 9
44 - 33= 11
<span> the answer is 33</span>
