Given: x+y= 15.
which of the following are ordered pairs of this equation?
{(-3, , , 16)}
{(-3, , , 14)
{(16, -, ,3)}

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

70 dollars is the answer
