Ahealth blog with 4,800 subscribers is doubling every 3 years. what will be the
number of subscribers after 12 years.

76,800 subscribers :)

Step-by-step explanation:

Initially: 4,800

3 years: If the number of subscribers is doubling every 3 years, all you have to do is multiply it by 2.

4,800 · 2 = 9,600

So, after 3 years, they have 9,600 subscribers.

6 years: Now that the health blog has 9,600 subscribers, you need to multiply THAT number by 2.

9,600 · 2 = 19,200

Now the blog has 19,200 subscribers

9 years: Now, we just repeat what we've been doing for the other 6 years: multiply the blog's current subscriber count by 2.

19,200 · 2 = 38,400

12 years: Once more and we'll have our answer! Sub count is 38,400. Now double it.

38,400 · 2 = 76,800

Hope this helps! :)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
