Answer:
-3
Step-by-step explanation:
we know that
log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1
log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2
If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P
the answer is
the relationship between P and M is
M = 10000P
Answer: 3
To check:
2 * 3 = 6
1)
2(a + 3) = -12
Divide by 2
a + 3 = -6
Subtract 3
a = -9
2)
3(p + 2) = 18
Divide by 3
p + 2 = 6
Subtract 2
p = 4
3)
4(2r + 8) = 88
Dive by 4
2r + 8 = 22
Subtract 8
2r = 14
Divide by 2
r = 7
4)
2(3a + 2) = -8
Divide by 2
3a + 2 = -4
Subtract 2
3a = -6
Divide by 3
a = -2
5)
4(k + 3) = 4
Divide by 4
k + 3 = 1
Subtract 3
k = -2
You multiply 10.5 by 20 and get 210, that is your answer.
