Answer:

It isn't?

Step-by-step explanation:

Step 1:

x + 8y = 21

x + 8y - 8y = 21 - 8y

x = -8y + 21

Step 2:

(-8y + 21) + 8y = 21

-8y + 21 + 8y = 21

21 = 21

You are given the distance of the horse of 45 miles at 15miles per hour and another 35 miles at 10 miles per hour. You are asked the total time in hours of the cowboy riding his horse. You have to get the time each mile the cowboy rode.  

45 miles/15 miles per hour = 3 hours
35 miles/10 miles per hour = 3.5 hours
<span>3 hours + 3.5 hours = <u>6.5 hours</u>

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.
