How I can answer this question, NO LINKS, if you answer correctly I will give u brainliest!

20 times.

Skills needed: Cancelling out Like Terms, Division

Step-by-step explanation:

1) To find out "many times as large as" a number is, we utilize division.

2) Therefore we can divide the 1st expression by the 2nd expression

This is what we need to solve:

Let's break it down into two parts: The left part, which is , and the right part, which would be .

The left part is really easy to solve out:

3) The harder right part:

Now, we can evaluate to be 1000, and to be 100, and then divide, but that is not the most efficient method.

Let's use an exponent rule:

Let's use that for

--->

Therefore, the right part equals 10.

4) The final product is =

Therefore, 20 is the answer.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
