It takes the high-speed train x hours to travel the z miles from Town A to Town B at a constant rate, while it takes the regular
tatyana61 [14]

Answer:

S=  z (y-x)/(x+y)

Step-by-step explanation:

Lets the speed of high speed train = u

Lets the regular speed train = v

We know that

Distance = Speed x time

For high speed train

 z = u .x      

    u= z/x                  ----------1

For regular speed train

 z = v .y    

v = z/y             -------------2

Both are traveling in opposite direction so relative speed

Vr = z / x+ z /y

Lets in time t they will meet

z = (z / x+ z /y) t

t= xy/ (x+y)

Lets take distance  cover by high speed train is m when it moves A to B and  speed cover by regular train is n when it is moving B to A.They meet at time t.

m = u .t

m = z / x .xy/ (x+y)

m = zy/ (x+y)            -----------3

n = v .t

n = z / y .xy/ (x+y)

n = zx/ (x+y)              -----------4

From equation 3 and 4

So

m - n= zy/ (x+y)   - zx/ (x+y)      

S=  z (y-x)/(x+y)

Option a is correct.

You order them least to greatest, then take out your mean, median, and mode. Then you've got your outliners left over.

Graph the line with 3/4 slope<br> passing through the point (2,-2).
S_A_V [24]

Answer:

Step-by-step explanation

x1 = 2, y1 = -2 and m = 3/4

y - y1 = m(x - x1)

y - (-2) = 3/4(x - 2)

y + 2 = 3/4(x - 2)

Multiply each term by 4

4y + 8 = 3(x - 2)

4y + 8 = 3x - 6

4y = 3x - 6 - 8

4y = 3x - 14

Brrunno [24]

Answer:

1/3 and 1.5

Step-by-step explanation:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15

There are 5 Multiples of 3 on the Spinner and 3 multiples of four.

5/15 is the probability for a multiple of 3 which can be simplified to 1/3

3/15 is the probability for a multiple of 4 which can be simplified to 1/5

Hope this Helps!
