Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
If P varies jointly as q, r and s - assume this is in direct proportion, then P ∝ qrs so P = kqrs where k is a constant.70 = k x 7 x 5 x 4 = 140k : k = 140/70 = 0.5When q = 2, r = 15 and s = 7 then,P = 0.5 x 2 x 15 x 7 = 105
It is an equation and if 4h-6 = 22 then h = 7
S = 2 pi r h + 2 pi r2S - 2 pi r2 = 2 pi r hh = (S - 2 pi r2) / (2 pi r)
Congratulations! You already have. h = S+r
r = 60 m/h t = 2 h D = r t = (60m/h) x (2h) = 120 mi
45-h equals 38 = 7
If v = r * h then> r = v / h
It depends on what "a r equals 8" means.

If: -7 = 7-2r Then: r = 7
Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
h = 63
You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
