Answer:

1.2 hours

Step-by-step explanation:

Given data:

Speed of the westbound train = 55 miles/hr

Speed of the eastbound train = 75 miles/hr

Since the trains are moving in the opposite direction their relative speed becomes,

55 miles/hr +75 miles/hr=130 miles/hr.

Since, time = distance / speed

Now the time taken for the two trains to be 156 miles apart

time = \frac{156 miles}{130 miles/hr} \\=1.2 hours

Hence, the time taken for the two trains to be 156 miles apart = 1.2 hours

The time that taken for the two trains is 1.2 hours.

The computation of the time taken for the two trains is shown below:

Given that

The westbound train travels 55 miles per hour.

And, the eastbound train travels 75 miles per hour.

So, the total speed is

= 55 miles per hour + 75 miles per hour

= 130 miles per hour

The distance is 156 miles

So, the time taken is

= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\  miles\ per\ hour}\\\\

= 1.2 hours

Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

Will give brainliest lots of points A is the midpoint of LB,Lb =6x-17 and AB=2x+3
NARA [144]
A is the mid point ==> AL = AB = 2AB
6x-17=2(2x+3) => 6x -17 = 4x +6 => 2x = 23 =>x=23/2
then just plug x into LB and AB

The function f is defined by f(x) = x^2 + 3x -10 , if f(x + 5) = x^2 + kx + 30, k=
boyakko [2]

Answer:

k = 13

Step-by-step explanation:

substitute x = x + 5 into f(x) , that is

f(x + 5) = (x + 5)² + 3(x + 5) - 10 ← expand squared factor using FOIL

          = x² + 10x + 25 + 3x + 15 - 10

         = x² + 13x + 30

compare this with f(x + 5) = x² + kx + 30

for the 2 expressions to be equal , then k = 13

zheka24 [161]

Answer:

b=9

Step-by-step explanation:

move the constant to the right which makes it 8b +5.04=77.04

then subtract 77.04 - 5.04 which = 8b = 72
