<h2>
Option D is the correct answer.</h2>
Step-by-step explanation:
For the first 5 hours of a trip, a plane averaged 120 kilometers per hour.
Distance traveled in first 5 hours = 5 x 120 = 600 km
Let the remainder time be t hours.
For the remainder of the trip, the plane traveled an average speed of 180 kilometers per hour.
Distance traveled in remaining hours = 180 x t = 180t
Total distance traveled = 600 + 180t
Total time taken = 5 + t
Average speed of entire journey = 170 km/hr
We have
Total distance traveled = Average speed of entire journey x Total time taken
600 + 180t = 170 x (5+t)
600 + 180t = 850 + 170t
10t = 250
t = 25 hours
Total time taken = 5 + 25 = 30 hours
Option D is the correct answer.
Answer:
n1=1,n2=4
Step-by-step explanation:
first divide both sides by 6 of the equation
=n^2-3n=4
n^2-3n-4=0..move the constant to the outerside
n^2-3n-4=0...write -3 as a difference
n^2+n-4n-4=0
factor out n
n×(n+1)-(4n-4)=0
nx(n+1)-4(n+1)=0
(n+1)×(n-4)=0
=n(+1=0)work out
n-4=0
n=-1
n-4=0
now solve for n
and the answer will be ;n1=-1,n2=4
Answer:
8x+4y
Step-by-step explanation:
so use the distributive property and multiply 4 into (2x+y), so you get
(2x*4) + (y*4) = 8x + 4y
