To find the density of racon all you have to do is to divide number of racoons with surface area because as name says you need to get x number of racoons per m^2
its own name tells you what you need to divide with what.
answer is:
20/10 = 2 raccoons per m^2
Very good job! They are all correct and it shows how you got the answer! ^_^ 100%
The answer would be
D.) 70.4
You're welcome :)
Answer:
11 hours
Step-by-step explanation:
Setting up a system of equations and using the substitution method will give you the number of hours used by each tap. Let a = time for tap A and b = time for tap B:
a + b = 12 (A and B fill a tank in 12 hours)
a = b - 10 (tap A takes 10 hours less than tap B)
Substitute 'b - 10' for 'a' in the first equation:
b - 10 + b = 12
Combine like terms: 2b - 10 = 12
Add 10 to both sides: 2b - 10 + 10 = 12 + 10 or 2b = 22
Divide by 2: 2b/2 = 22/2
Solve for b: b = 11 hours
Answer:
x > -3
Step-by-step explanation:
–3x + 6 < 15
Subtract 6 from each side
–3x + 6-6 < 15-6
-3x < 9
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 9/-3
x > -3
