Hi,
You just have to change z^25 to z^24 or z^27.

Answer:
<u>5x+10</u>
27x
Step-by-step explanation:
cross multiply
The answer is -34
Explication
2✖️(-12)-10
-24-10
-34
Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
Answer:
A. 12.4
Step-by-step explanation:
To find a, we'll use the Law of Sines that says:

And we'll isolate a to get:

We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:
A = 180 - 90 - 16.75 = 73.25
(converted 16°45' to 16.75)
Then we will plug-in the information we already have

So, let's round it to 12.4 to match the answer A.
