Answer:

its b.

Step-by-step explanation: 5n − 19 + n + 7 = 144 − 6n

6n − 12 = 144 − 6n

12n = 156

n = 13

m∠z = (144−6n)°

m∠z = (144−6×13)°

m∠z = 66°

Identify the graphical solution to the inequality
NeTakaya

Answer:

A

Step-by-step explanation:

to solve absolute value inequalities you must solve it for when the absolute value is positive and then when it is negative

example, |4| = 4 and -4

first solution will be when we're solving for the positive value:

+(-4x+7) ≥ 27

-4x + 7 ≥ 27

-4x ≥ 20

x ≤ -5   [reverse the symbol when mult or div by a negative]

-(-4x+7) ≥ 27

4x - 7 ≥ 27

4x ≥ 34

x ≥ 34/4 or x ≥ 8 1/2

solution:  x ≤ -5 or x ≥ 8.5

Find the total cost of a spa treatment of $42 including 6% sales tax and 20% tip
Naily [24]
Cost of the spa treatment = $42
Percentage of sales tax = 6%
Percentage of tips = 20%
Normally the tips amount is calculated before adding sales tax.
Then
Amount of tips given = (20/100) * 42
                                  = (1/5) * 42
                                  = 8.40 dollars
Amount of sales tax taken = (6/100) * 42
                                           = 252/100
                                           = 2.52 dollars
Then 
The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars
                                                                   = 52.92 dollars
So we can see that $52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.

Can y’all help me on Thai one
natima [27]

Answer:

20.

$18.40.

Step-by-step explanation:

The mean number of people = (12+19+17+26+26)/5

= 100/5

= 20.

Karmin's original hourly rate = 480/30

= $16 per hour.

With a 15% rise it is 16 * 1.15

= $18.40 / hour.
