Answer:

x=-32

Step-by-step explanation:

So we have the equation:

x-2(x+10)=12

Distribute the -2:

x-2x-20=12

Combine like terms:

-x-20=12

Add 20 to both sides:

-x=32

Divide both sides by -1:

x=-32

And we're done!

The seismic activity density of a region is the ratio of the number of earthquakes during a given time span to the land area aff
Karolina [17]

The correct statement about the earthquake in the state is option c. State A had approximately 3,362 more earthquakes than State B.

<h3>How to solve for the earthquake in the state A</h3>

we have x/y = 0.00299

y = 163696

To solve for x we have

163696 * 0.00299

= 4895 earthquakes

<h3>Next we have to solve for earth quakes in state B</h3>

x = 0.1402 x 10931

= 1533

Next we have to find the difference

4895 - 1533 = 3362 earthquakes.

We have to conclude that state A has 3362 earthquakes more than B. Hence the answer is c.

2/4 of an hour is how many minutes
elena-14-01-66 [18.8K]

Answer: 30 minutes

Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.

Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.

Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>

We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.

Therefore, 2/4 of an hour is 30 minutes.
