Answer:

x= 13.5

Step-by-step explanation:

f(x) = 2x + 9

f(x) = 36

Set the 2 equations equal to each other;

2x + 9 = 36

Subtract 9 from both sides;

2x = 27

Divide both sides by 2;

x = 13.5

<em>Check:</em>

f(x) = 2x + 9

f(13.5) = 2(13.5) + 9= 27 + 9 = 36

Ellen plans to leave an 18 percent tip with her $23.75 lunch bill. Which of these expressions could she use to determine her tot
Makovka662 [10]

You probably forgot to mention the options. After a little research, I was able to get the complete question with the mentioned options you should have mentioned. The potential complete question is:

<em>Ellen plans to leave an 18 percent tip with her $23.75 lunch bill. Which of these expressions could she use to determine her total bill? </em>

<em>Check all that apply. </em>

<em>(1.18)(23.75) 23.75 – [(0.18)(23.75)] 23.75 + [(0.18)(23.75)] (0.18)(23.75)</em>

<em />

Answer:

The expression 23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right] will determine her total bill.

Step-by-step explanation:

Total lunch bill = $23.75

As he pans to 18% tip of the total bill, so the expression will be:

=23.75\:+\:\left(\:18\%\:\:of\:\:23.75\:\right)

=23.75\:+\:\left(\:\frac{18}{100}\:\times \:23.75\:\right)

=23.75\:+\:\left(\:0.18\times \:23.75\:\right)

or

=23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right]

Therefore, the expression 23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right] will determine her total bill.
