Suppose logbx = logcx, where b ≠ c. then the value of x can be a) 0 only b) 1 only c) b^c or c^b only d) any positive real number

Not A: We can't have because is undefined for a logarithm of any base.

B is true: for any base.

Not C: If , then , but which only reduces to if . This can only happen if , however, but we've assumed otherwise.

Not D: The reasoning for C not being correct is enough to rule out this possibility.

i believe the answer is letter c) 8

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
