Answer: 431 reserved seats were sold.
Step-by-step explanation:
<h3>4(1787-y)+3y = 5792
</h3><h3>7148-4y+3y = 5792</h3><h3>x+1356=1787
</h3><h3>x=431</h3><h3 /><h3>Hope this helps :)</h3>
Consider a geometric sequence

let

and the common ratio be r, then the sequence is constructed as follows:

we can observe that each term of the sequence is its previous term * r.
In the given sequence, to find the common ratio we divide 6,561 by −2,187 and get -3. This means that

Let the first term

,
then the eighth term is

Answer: -3
Answer:
option 2 must be the correct answer because the two figure are congruent figure.
If the slope of the number is positive (the graph goes upward from left to right), then m will be positive, but if the slope is negative (the graph goes downward from left to right), then m is negative. So, no. M does not have to be a positive number, it may also be negative.
Oh, this is really easy!
Okay so the formula for the pythagorean theorem is a²+b²=c<span>²
So it doesnt really matter whats a or b
So take 21</span>²+15²=c<span>²
That ends up being 441+225=c</span><span>²
so next take 441+225 and that equals 666 then you have to find the square root so the square root of 666 is 25.81
S the answer is 25.81 </span>
