flying to munich with a tailwind plane averaged 242 mph. on the return trip the plane only averaged 178 mph while flying back in
Romashka [77]

Answer:

The speed of wind is 32 mile per hour

The speed of plane is 210 mile per hour

Step-by-step explanation:

Given as :

The speed of plane with tailwind = 242 mph

The speed of the return trip = 178 mph

Let The speed of the wind = y mph

The speed of the plane = x mph

Now , According to question

The speed of plane with tailwind = x + y

Or, x + y = 242 mph         .......1

and The speed of the return trip = 178 mph

or ,  x - y = 178 mph         ........2

Solving both equations

( x + y ) + ( x - y ) = 242 + 178

Or, 2 x = 420

∴  x = \frac{420}{2}

I.e x = 210 mph

Put the value of x in eq 1

I.e x + y = 242 mph

or, 210 + y = 242

∴  y = 242 - 210

I.e y = 32 mph

Hence The speed of wind is 32 mile per hour

And The speed of plane is 210 mile per hour   Answer

What is the x and the y
Ghella [55]

Answer:

x=5\\\\y=-8

Step-by-step explanation:

Given Equation:

-7x-10y=45\\\\ Equation:1

-3x-5y=25   Equation:2

Multiplying Equation:2 by '2':

-6x-10y=50  Equation:3

Using Elimination Method: Subtracting Equation:1 from Equation:3:

-6x-10y-(-7x-10y)=50-45

-6x-10y+7x+10y=5\\\\

Solving Like terms:

-6x+7x=5\\\\x=5

Put the value of 'x' in Equation:2

-3x-5y=25

-3(5)-5y=25\\\\-15-5y=25

Adding '15' both sides:

-5y=25+15\\\\-5y=40

Dividing by '-5' both sides:

y=40/-5\\\\y=-8

The values of 'x' and 'y' are:

x=5\\\\y=-8
