Solve by the substitution method x-7y=-47, -6x-8y=-18

x is -5 ; y is 6

x=-47+7y

-6x-8y=-18

-6(-47+7y)-8y=18

y=6

x=-47+7*6

x=-5

the statemwnt is the company makes small and large snow cone cups.

large=it holds more then the small

small=it holds less then the large

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.
