x = 1 and y = 6 so the lines intersect at the point (1, 6)
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
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)
Ordered pair 20 10 means x is 20 and y is 10, written as (20,10).
20 = 400
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.
The factor pair is (2,10)
20 plus 20 equals 4020 plus 20 = 40
Yes.
803 + 20 = 823823 - 100 = 723803 plus 20 minus 100 equals 723.
205
20 percent is equivalent to .20 multiply 280 by .20 equals 56 280 plus 56 equals 336
-15 plus 20 is 5.
