Which ordered pair is a solution to mx +ny = 0?

(x, -(m/n)*x )

Step-by-step explanation:

We need to find the ordered pair that is solution to:

mx +ny = 0

Rearranging,

ny = -m*x

y = -(m/n)*x

The ordered pair is

(x, -(m/n)*x )

In the image below, we can see an example for m = 2 and n = 1

The angles in a triangle always add to 180°.therefore: (2x) + (2x + 9) + (3x - 11) = 1802x + 2x + 9 + 3x - 11 = 180(2x + 2x + 3x) + (9 - 11) = 1807x - 2 = 180    |+27x = 182    |: 7x = 262x = 2 · 26 = 522x + 9 = 2 · 26 + 9 = 613x - 11 = 3 · 26 - 11 = 67answer: the measure of the smallest angle is 52°.
