It would be the first one because it says that there are 4 times as many red roses as pink roses and so that would be represented r=4p
Hope this helps! Good luck!
Commonsense you do math in your mind
2x + 3x + 5x = 60
10x = 60
a = 6
Shortest side = 2x = 12 inches
Direct variation has the form y=kx. Given a point we can solve for the constant k.
y=kx, when y=9 and x=-3 becomes:
9=-3k
k=-3 so the constant of variation is negative 3
