Which of the following represents "the sum of the abscissa and the ordinate is six"?

x+y=6

Step-by-step explanation:

In two dimensional graph we have 4 quadrants with two mutually perpendicular lines cutting the region into 4 quadrants.

The x coordinate of any point is called abcissa and y coordinate of the point is ordinate.

Sum of abscissa and ordinate = x+y when written as an algebraic expression

Since given that The sum of the abscissa and the ordinate is six

we have as

x+y =6

Hence answer is

x+y =6

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.
