To answer your question, the answer would be 8
Answer:65
Step-by-step explanation:
I'm not sure what you mean by "expression form," but if its simpliest form, you would simply do 20+5*9, and 5*9 is 45. 45+20 is 65
Answer:
Well the divisibility rule for 22 is that the number must be divisible by 2 and 11. In order for something to be divisible by 2 it needs to end in 0, 2, 4, 6, or 8. For the number 11 the, if the difference between the odd numbered digits and the sum of the even numbered digits is a multiple of 11 then it is divisible by 11.
So I would say no for both of them since 22 is divisible by 11.

The density of water is about 1g/cm3
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
