Answer:
Step-by-step explanation:
let their ages be x,y,z and x>y>z
x+y+z=74 ...(1)
x=(y+z)-12
or x-y-z=-12 ...(2)
y=z+5 ...(3)
add (1) and (2)
2x=62
x=62/2=31
from (1)
31+y+z=74
y+z=74-31=43
substitute from (3)
z+5+z=43
2z=43-5=38
z=38/2=19
y=19+5=24
so their ages are 31,24 and 19
Answer:
4000Pa
Step-by-step explanation:
Pressure is force(thrust) per unit area.
Pressure=Force/Area
P=F/A
A.T.Q
Applied force=800N
Area=0.2m²
Pressure=800/0.2=4000Pa
Answer:
Step-by-step explanation:
50 * 5x = 5000
Dividing both sides by 50
=> 5x = 5000/50
=> 5x = 100
Dividing both sides by 5
=> x = 20
