Answer:
125
Step-by-step explanation:
log2 (24) - log2 (3) = log5 (x)
We know that log a(b) - log a(c) = log a( b/c)
log2 (24/3) = log5 (x)
log2 (8) = log5 (x)
Rewriting 8 as 2^3
log2 (2^3) = log5 (x)
We know that log a ( a^b) = b loga (a) and loga (a) =1
3 log2 (2) = log5 (x)
3 *1 = log5 (x)
3 = log5 (x)
We know log a (b) =c can be written as a^c =b
5^3 = x
125 =x
I think it’s seventy five
Answer:
7 minutes
Step-by-step explanation:
1000 stairs in 25 minutes
280 stairs in 280*25 / 1000 = 7 minutes
Answer:
s = -1
Step-by-step explanation:
7 = -10s - 3
==> add 3 to both sides
10 = -10s
==> divide both sides by -10
-1 = s
