-11t=15-6t, please help me.​

Mathematics
1 answer:
user100 [1]2 years ago
7 0

Answer:

t = -3

Step-by-step explanation:

15 - 6t = -11t

ADD 6t TO BOTH SIDES

15 = -5t

DIVIDE -5 TO BOTH SIDES

t = -3

Do you see how I got t = -3? Do you fully understand it, so if you get another question like this, you won't need help? I hope this helps! :)

You drive from your home to a vacation resort 420 miles away. You return on the same highway. The average velocity on the return
attashe74 [19]
<h2>Time required to complete the round​ trip T=\frac{420}{x}+\frac{420}{(x-15)} where x is average velocity on the outgoing​ trip.</h2>

Step-by-step explanation:

Let average velocity of outgoing trip = x mph

The average velocity on the return trip is 15 miles per hour slower than the average velocity on the outgoing trip.

Average velocity of return trip = (x-15) mph

Distance to vacation place = 420 miles

Distance to vacation place = Time for outgoing trip x average velocity of outgoing trip

          420=t_1\times x\\\\t_1=\frac{420}{x}

Distance to vacation place = Time for return trip x average velocity of return trip

          420=t_2\times (x-15)\\\\t_2=\frac{420}{(x-15)}  

We have total time T = t₁ + t₂

That is

                     T=\frac{420}{x}+\frac{420}{(x-15)}

Time required to complete the round​ trip T=\frac{420}{x}+\frac{420}{(x-15)} where x is average velocity on the outgoing​ trip.

Ray UW is the angle bisector of AngleVUT.
tester [92]

Answer:

AngleWUT =38°, option 2

Step-by-step explanation:

We have three rays passing through U. A ray is set extend in one direction with one fixed point.

We have UW ray bisecting VUT.As the ray bisects the angle between VUW and WUT would be same .

Given angles are (4x+6)° and (6x-10)°.

As these angles are equal

4x+6=6x-10

2x=16

x=8

AngleWUT = (6x – 10)°

and x is 8 so on substituting AngleWUT =38°.
