Answer:

x = 58

Step-by-step explanation:

The 2 angles form a straight angle and are therefore supplementary, thus

x + 6 + 2x = 180, that is

3x + 6 = 180 ( subtract 6 from both sides )

3x = 174 ( divide both sides by 3 )

x = 58

You leave a 15% tip of $3.12. How much was the bill?

dangina [55]

Answer:

$3.61 cents

Step-by-step explanation:

Given the following question:

15% of 3.12

To find the answer we use the formula to calculate percentages, then we add that answer to the initial bill.

$\frac{p\times n}{100}$
$\frac{15\times3.12}{100} =15\times3.12=46.8\div100=0.468$
$=0.468$

<u>Round:</u>
$0.468$
$8 > 5$
$0.47$
$t=0.47$

<u>Now add:</u>
$3.14+0.47=3.61$
$=3.61$

After leaving a 15% tip, the total amount you would pay is "$3.61 cents."

Hope this helps.
