Eurostar is a high-speed railway service connecting
erma4kov [3.2K]

Answer:

Step-by-step explanation:

This is simply a units conversion problem.  It gives us for the number of passengers, the number of seats per carriage and the number of carriages per train.  To change the units from passengers to trains without changing the value, we use the multiplicative identity (that is, 1).

350000 passengers

(350000 passengers) * 1

(350000 passengers) * ((1 carriage)/(32 passengers)) * ((1 train)/(15 carriages)

   [note:  passengers and carriages cancel. Leaving only trains]

(350000)*(1/32)*(1/15) trains       [note: I write this way to paste into MS Excel]

729.1667  trains                 [oh, but don’t just round this number either up or down]

   729 full trains can carry 729*32*15 = 349920 passengers

   730 full trains can carry 730*32*15 = 350400 passengers

Now, we can say that 730 trains are adequate to carry 350000 passengers.

use the elimination method to solve the system of equations choose the correct ordered pair 7x+4y=39 2y+4y=14
Anvisha [2.4K]

x = 5 \: and \: y = 1.

Step-by-step explanation:

7x + 4y = 39 \:  -  {eq}^{n} (1)

2x + 4y = 14  \: \:  -  {eq}^{n} (2)

Multiply Equation no (1) with 2 and Equation no (2) with 7.

14 x + 8y = 78.

14x + 28y = 98.

( - ) \: \:  \:  ( - ) \:  \:  \: ( - )

0x +  -20y =  - 20

- 20y =  - 20

y =  \frac{ - 20}{ - 20}

y = 1

Substitute the value of "y" in Equation no (1)

7x + 4y = 39.

7x + 4(1) = 39.

7x + 4 = 39.

7x = 39 - 4

7x = 35.

x =  \frac{35}{7}

x = 5.
