5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair

Ordered pair 20 10 means x is 20 and y is 10, written as (20,10).

1 plus 19 equals 20 2 plus 18 equals 20 3 plus 17 equals 20 4 plus 16 equals 20 5 plus 15 equals 20 6 plus 14 equals 20 7 plus 13 equals 20 8 plus 12 equals 20 9 plus 11 equals 20 10 plus 10 equals 20 1 times 20 equals 20 2 times 10 equals 20 4 times 5 equals 20

2y + 2x = 20 y - 2x = 4 Add the two equations: 3y = 24 so that y = 8 Substitute this value of y in the second equation: 8 - 2x = 4 then 4 = 2x so that x = 2 Thus the ordered pair (y,x) = (8,2)

20 plus 20 equals 4020 plus 20 = 40

The factor pair is (2,10)

Yes.

205

Of course!

-20

-15 plus 20 is 5.

1985 plus 20 is 2005

Negative 15 plus positive 20 equals 20 minus 15, which equals 5.

803 + 20 = 823823 - 100 = 723803 plus 20 minus 100 equals 723.

There are an infinite number of ordered pairs that answer that question correctly. Since you're not letting me see the list of choices that goes with the question, the probability of my coming up with the correct one from that list is zero.

20 percent is equivalent to .20 multiply 280 by .20 equals 56 280 plus 56 equals 336

A equals 20.
