Answer:
x = 5/4
Step-by-step explanation:
32^(x-1) = 16^(x/4)
(2^5)^(x-1) = (2^4)^(x/4) . . . . . express as powers of 2
2^(5x -5) = 2^x . . . . . . simplify
5x -5 = x . . . . . . equate exponents
4x = 5 . . . . . . . . add 5-x
x = 5/4

32.85 is the answer you just multiply
Answer:
46.25%
Step-by-step explanation:
First, add both numbers together. (86 + 74).
Next, we have 160. And that is 100%.
Now, we have to find what 74 is compared to 160.
74 is 46.25% of 160.
There's our answer.
