Show all Work; Solve using the substitution method: y=x-6 3x-2y=8

1 answer:

3 0

Step-by-step explanation:

$y = x - 6...(1) \\ 3x - 2y = 8...(2) \\ substituting \: y = x - 6 \: in \: equation \: (2) \\ 3x - 2(x - 6) = 8 \\ 3x - 2x + 12 = 8 \\ x = 8 - 12 \\ x = - 4 \\ \implies \: y = x - 6 = - 4 - 6 = - 10 \\ \therefore \: y = - 10 \\ \therefore \: \{x, \: \: y \} = \{ - 4, \: \: - 10 \}$

A jet plane can carry up to 200,000 liters of fuel. It used 130,000 liters of fuel during a flight. What percentage of the fuel

-Dominant- [34]

Given:

Capacity of jet plane = 200,000 liters of fuel

Fuel used during flight = 130,000 liters

To find:

The percentage of the fuel capacity it uses on this flight.

Solution:

According to the question, we need to find 130,000 is what percent of 200,000.

$\text{Required percentage}=\dfrac{\text{Fuel used during flight}}{\text{Capacity of jet plane}}\times 100$

$\text{Required percentage}=\dfrac{130000}{200000}\times 100$

$\text{Required percentage}=65$

Therefore, the jet plane uses 65 percent of fuel capacity during flight.
