5x - 3y = 36 2x + 3y = -15

x = 3

y = -7

Step-by-step explanation:

(3, - 7 )

Step-by-step explanation:

Given the 2 equations

5x - 3y = 36 → (1)

2x + 3y = - 15 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

7x + 0 = 21

7x = 21 ( divide both sides by 7 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

5(3) - 3y = 36

15 - 3y = 36 ( subtract 15 from both sides )

- 3y = 21 ( divide both sides by - 3 )

y = - 7

solution is (3, - 7 )

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
