Answer 1

1) Multiply both top and bottom by 5...you get 10/15, so x=10

2) divide both top and bottom by 6 to get 3/5....s=3

Answer 2

Hello,

2/3 = x/15 multiply both sides by 15 giving us 30/3 = x or x = 10

18/30 = s/5 multiply both sides by 5 and we have 90/30 = s so s = 3

Hope This Helps!

Answer 3

y = 5 - 4(5) = 5 - 20 = -15; so we've (5, -15) y = 5 - 4(a million) = 5 - 4 = a million; so we've (a million, a million) y = 5 - 4(-a million) = 5 + 4 = 9; so we've (-a million, 9). So the lacking values are -15, a million, and 9, respectively.
