Answer: 7

Step-by-step explanation:

$(4+5)-2$

You can either remove brackets and just do a little addition and subtraction.

$4+5-2$

$9-2\\7$

So the answer is 7.

Or just finish things inside the brackets first.

$(4+5)-2\\9-2\\7$

So the answer is 7.

Answer: Third Option

$x=1.469743$

Step-by-step explanation:

We have the following exponential equation

$3^{x+1}=15$

We must solve the equation for the variable x

To clear the variable x apply the $log_3$ function on both sides of the equation

$log_3(3^{x+1})=log_3(15)$

Simplifying we get the following:

$x+1=log_3(15)$

To simplify the expression $log_3 (15)$ we apply the base change property

$log_b(y)=\frac{log(y)}{log(b)}$

This means that:

$log_3 (15)=\frac{log(15)}{log(3)}$

Then:

$x+1=\frac{log(15)}{log(3)}$

$x=\frac{log(15)}{log(3)}-1$

$x=1.469743$

At the movie theatre, child admission is $6.20 and adult admission is $9.30 . On Monday, 157 tickets were sold for a total sales

Andre45 [30]

C = child tickets
a= adult tickets

c + a = 157
6.20c + 9.30a = 1178.00

6.20c + 9.30a = 1178.00
-6.20c -6.20a = -973.40

3.10a = 204.60

a = 66 adult tickets

c + 66 = 157
-66. -66

c= 91 child tickets
