Answer:
27
Step-by-step explanation:
18 years ago she was 9 and 9 x 3 is 27
10450-270x=?
x=15
10450-270(15)=?
10450-4050=6400
there is 6400ml left in the tank after 15 minutes
Answer:
28%
Step-by-step explanation:
Answer:
x = -1/2 or x = (2 i π n)/log(36) - 1/2 for n element Z
not sure what you needed but I gave both solutions.
Step-by-step explanation:
Solve for x over the real numbers:
216 = 36^(1 - x)
216 = 36^(1 - x) is equivalent to 36^(1 - x) = 216:
36^(1 - x) = 216
Take reciprocals of both sides:
36^(x - 1) = 1/216
Take the logarithm base 36 of both sides:
x - 1 = -3/2
Add 1 to both sides:
Answer: x = -1/2

Take reciprocals of both sides:
36^(x - 1) = 1/216
Take the logarithm base 36 of both sides:
x - 1 = (2 i π n)/log(36) - 3/2 for n element Z
Add 1 to both sides:
Answer: x = (2 i π n)/log(36) - 1/2 for n element Z
