30t=50(t-1)
30t=50t-50
30t-50t=-50
-20t=-50
t=-50/-20
t=2.5 hours after the freight train leaves the station they will meet

Answer:

after 2.5 hour passenger train would overtake .

Step-by-step explanation:

A freight  train leaves a station at noon traveling at 30 mph.

A passenger train leaves 1 hour later travelling at 50 mph

Let the time to leave the station of freight train = t

time to leave passenger train = t - 1

Since distance = speed × time

the expression will be :

30t = 50(t - 1)

30t = 50t - 50

30t - 50t = -50

-20t = -50

t = \frac{-50}{-20}

t = 2.5 hours

After 2.5 hours passenger train would overtake the freight train.

The sum of two numbers is 48.when the smaller number is subtracted from the larger number,the difference is 12. What are the two
Savatey [412]

Answer:

The two numbers are:

30 and 18

Step-by-step explanation:

a + b = 48

a - b = 12

From the first eq.

a = 48 - b

Replacing this last value in the second eq.

(48 - b) - b = 12

48 - 2b = 12

48 - 12 = 2b

36 = 2b

36/2 = b

18 = b

from the first eq.

a + 18 = 48

a = 48 - 18

a = 30

Check:

from the second eq.

a - b = 12

30 - 18 = 12

Find the value of x and the value of y
erik [133]
The triangle is an isosceles triangle with exactly two congruent angles.
Since the two 45-deg angles are congruent, their opposite sides are also congruent. That makes y = 5.

This triangle is a 45-45-90 triangle. In a 45-45-90 triangle, the legs are congruent and the hypotenuse is sqrt(2) times the length of the legs.
The hypotenuse has length x, so x = 5 * sqrt(2) = 5sqrt(2)

Answer: B. x = 5sqrt(2), y = 5
