Hello!

Let's begin with question 1, 2a(x) · b(x) = ?

2(3x - 1) · $2^{x}$

$2^{x}$ · (6x - 2)

Question 2, a(x) + 2b(x) = ?

3x - 1 + 2( $2^{x}$ )

Question 3, $\frac{b(x)}{2a(x)}$ = ?

$\frac{2^{x}}{2(3x - 1)}$

$\frac{2^{x}}{6x - 2}$

Question 4, 2a(x) + b(x) = ?

2(3x - 1) + $2^{x}$

6x - 2 + $2^{x}$

Question 5, a(x) - b(2x) = ?

3x - 1 - $2^{2x}$

Your cousin Pablo gets his haircut, and it costs $12.00. What will he spend in total on his haircut if he includes a 12% tip?

sattari [20]

Answer:

The tip would be $1.44, so the total would be $13.44

Step-by-step explanation:

To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
