What is the value of x in the solution to this system of equations?
3x - 5y = 22
y=-5x +32

y= -2

x=4

3×4=12, 5×-2 = -10

12- (-10)= 22

3×4 - 5×(-2) = 22

better mark me brainlest. i stopped studying just to work this out.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
