Answer:
Step-by-step explanation:At the start of the question the population of the lake was 60 fish 1 year ago.
In one year the population dropped 25%.
25% of 60 is 15.
60 minus 15 equals 45
Answer:
x = 2
Step-by-step explanation:
The relevant rule of logarithms is ...
log(a/b) = log(a) -log(b)
This lets us combine the logs on the left to get ...
log((6 +7x)/(3x -2)) = log(5)
Taking anti-logs gives ...
(6 +7x)/(3x -2) = 5
6 +7x = 5(3x -2) . . . . . multiply by (3x -2)
7x +6 = 15x -10 . . . . . eliminate parentheses
8x = 16 . . . . . . . . . . . add 10-7x to both sides
x = 2 . . . . . . . . . . . . . divide by 8
The solution is x = 2.
_____
The graph shows the left side of the equation is equal to the right side for x=2.
The answer is 42 becuase you are making 53 groups of 2226 you can also simply solve it by useing long division
Answer:
k > -2
Step-by-step explanation:
Step 1: Write inequality
6 > -2k + 2
Step 2: Solve for <em>k</em>
- Subtract 2 on both sides: 4 > -2k
- Divide both sides by -2: -2 < k
- Rewrite: k > -2
Here we see that any number greater than -2 will work. So numbers like 4, 9, 1249, or even 1957893402678 would work.
