The answer is 45/8
You have make sure that the denominator has the same value!
31/4-17/8=62/8-17/8
=45/8
Answer:
x=-2
Step-by-step explanation:
Answer:
12 gallons
Step-by-step explanation:
If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.
From the given points on the graph we can find which function represents this graph.
A point on the graph is (3, 1). This means if we substitute x = 3 the answer must be 1.
The property of log is that
This suggests, if the base of log is equal to the number for which we are finding the log, the answer must be 1.
So, in this case we have:
Since the answer is 1, the base of log must be 3.
In the given options, only option 3rd is with base 3.
So, the correct answer is option 3.
D. The fourth choice is correct.
