30/100 = 15/x
cross multiply
1500 = 30x
1500/30 = 50
Answer:
2
Step-by-step explanation:
Let, Lou's set = x
g(x) = 3 + 5x
x = 0,..
3, 8, 13, 18, 23, 28, 33
set y:
g(y) = 39 - 6x
x = 0,...
(39, 33, 27, 21, 15, 9, 3)
Numbers in common :
(3, 33)
= 2
Answer:
21
Step-by-step explanation:
Answer:
15 in - (1.25 in/hr)t
Step-by-step explanation:
L(t) is a function of time, t: L(t) = 15 in - (1.25 in/hr)t
Note that when the candle has burned down to nothing, L(t) = 0. How long does that take? Set 15 in - (1.25 in/hr)t equal to zero and solve for t:
(1.25 in/hr)t = 15 in, or
15 in
t = ---------------- = 12 hrs
1.25 in/hr
2/5 divided by 5/6 is 12/25
6/7 divided by 2/14 is 6
4 2/3 divided by 1/2 is 9 1/3
