Answer:

x = $\frac{5}{7}$

Step-by-step explanation:

We can start simplifying this equation by expanding the parenthesis and cross multiplying.

$(7^x)^4 = \frac{7^2 * 7^3}{7^{3x}} = \\\\\\7^{4x} = \frac{7^5}{7^{3x}}\\\\\\7^5 = 7^{7x}\\\\\\$

The exponent 5 and 7x are equal:

$\longmapsto$ Divide both sides by 7

$5 = 7x\\\\x = \frac57$

A movie theater sells tickets at different prices. Adults are charged $8.50 per ticket, and children are charged $5.50 per ticke

AlladinOne [14]

Answer:

9 child tickets and 17 adult tickets were sold.

Step-by-step explanation:

Let the number of adult tickets sold be $a$

and the number of child tickets be $c$ .

The theater sold a total number of 26 tickets.

This means that: $a+c=26$ .....eqn1

The theater made a total sale od $194.

This implies that:

$8.5a+5.5c=194$ ...eqn2

We make $a$ the subject in equation 1: $a=26-c$ ...eqn3

Substitute equation (3) into equation (2)

$8.5(26-c)+5.5c=194$

Expand to get: $221-8.5c+5.5c=194$

$-8.5c+5.5c=194-221$

$-3c=-27$

$\implies c=9$

Put c=9 into equation (3) to get: $a=26-9=17$

Therefore 9 child tickets and 17 adult tickets were sold.
