Answer + ! which ordered pair (x, y) is a solution to the following system of equations? a. (–6, 4) b. (2/7, 18/7) c. (18/7, 2/7) d. (6, -2)

  A.  (–6, 4)

Step-by-step explanation:

If you try the answer choices in the equations, you find the first one works.

__

The task of checking the possible answers can be made easier by dividing the common factor from the second equation:

  x + 2y = 2 . . . . . . . divide the given equation by 3

It is easy to see that only choice A will satisfy this equation.

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
