Answer:
4.95m
Step-by-step explanation:
Let the length of longer and shorter pipe be x and y respectively..
given,
x/y=9/2...(i)
x-1.65=3y ...(ii)
in eqn ii..
x-1.65=3y
or, x/y - 1.65/y = 3
or, 9/2-1.65/y =3
or, 4.5-3 = 1.65/y
or, y=1.65/1.5
•°• y = 1.1m
now,
x/y = 9/2
or, x/1.1 = 4.5
x= 4.5×1.1
•°• x= 4.95m
thus, the length of the longer pipe is 4.95m
Answer: 15 ways
Step-by-step explanation: 5+4+3+2 + 1 = 15
Answer:
y=-1/3x-5
Step-by-step explanation:
y=mx+b is equation of line where m is slope and b is y-intercept.
From question statement, we observe that
m= -1/3 , b= -5
put above values in equation of line, we get
y= -1/3x-5.
