What are the coordinates (x, y) at which the graphs of 2x + 3y = 12 and 2x - y = 4 intersect?
a. (3, 2)
c. (1, -2)
(2,3)
d. (-3, 6)
Letter answers only pls.

  The coordinates (x,y) are (3,2), If the graphs of and are intersect.

Step-by-step explanation:

The given is,

                                         .................................(1)

                                           ....................................(2)

Step:1

            The values of x and y are obtained by elimination method,

            Substrate the equation (1) and (2),

             ( - )

             Equation becomes,

            From the equation (1),

Step:2

            Check for solution,

                                          ....................................(2)

            Substitute the values of x = 3 and y = 2 in above equation,

           Both sides are equal, so the x = 3 and y = 2 is correct answer

Result:

          The coordinates (x,y) are (3,2), If the graphs of and are intersect.

3.0

Step-by-step explanation:

If the ratio is boys to girls, in fraction form (ratio form) that's

When we set up the ratio using the numbers, we have to keep the boy stuff with the boy stuff on top, and the girl stuff with the girl stuff on bottom.  So the ratio with the given numbers is

Reducing that down to decimal form, since 12 is divisible by 4 evenly, would be 3.0
