D. 12 + 13 = 25,

Why you ask? Because the inverse operation of addition is subtraction.

Answer:

$\frac{9x}{y^3}$

Step-by-step explanation:

$\frac{\left(3x^2y^4\right)^3}{3x^5y^{15}}$

$(3x^2y^4)^3 : 3^3x^6y^1^2$

= $\frac{3^3x^6y^{12}}{3x^5y^{15}}$

$\frac{3^{3} }{2} = 3^{2}$

= $\frac{3^2x^6y^{12}}{x^5y^{15}}$

= $\frac{x^{6} }{x^{5} } : x$

= $\frac{3^2xy^{12}}{y^{15}}$

= $\frac{y^{12} }{y^{15} } : \frac{1}{3{y} }$

= $\frac{3^2x}{y^3}$

$3^2=9$

= $\frac{9x}{y^3}$

Answer:

<u>875</u> student tickets were sold.

Step-by-step explanation:

Given:

The drama club sold 2100 tickets to their last play.

Student tickets were $5 and adult tickets were $7.

They collected $12,950.

Now, to find the number of student tickets sold.

Let the number student tickets be $x.$

And the number adult tickets be $y.$

So, the total number of tickets:

$x+y=2100\\y=2100-x$

Now, the total amount collected:

$5x+7y=12950$

Putting the value of $y$ from above:

$5x+7(2100-x)=12950$

$5x+14700-7x=12950$

$14700-2x=12950$

<em>Subtracting both sides by 14700 we get:</em>

$-2x=-1750$

<em>Dividing both sides by -2 we get:</em>

$x=875.$

The number of student tickets = 875.

Therefore, 875 student tickets were sold.

Given that (7-2x),9,(5x+17) are consecutive terms of a geometric progression with common ratio, r>0, find the value of x.

andre [41]

This are also referred to as exponential sequence. The common ratio if r > 0 is 2

<h3>Geometric sequence</h3>

This are also referred to as exponential sequence. Given the following sequence

(7-2x),9,(5x+17)

If they are in geometric progression, hence;

9/7-2x = 5x+17/9

Cross multiply

7-2x(5x+17) = 9(9)

Expand

35x+119-10x²-34x = 81

-10x²+x+119-81=0
10x²-x-38 = 0

Factorize

10x²-20x +19x-38 = 0

10x(x-2)+19(x-2)= 0

x - 2 = 0

x = 2

Hence the common ratio if r > 0 is 2
