here's the solution,

<em><u>first term </u></em>(a) :

=》 -2x - 9

<em><u>common difference</u></em> (d) :

=》 -5x - 5 - (-2x - 9)

=》 -5x - 5 + 2x + 9

=》 -3x + 4

now,

10th term :

=》a + (n - 1)d

=》-2x - 9 + (10 - 1) × (-3x + 4)

=》-2x -9 + (9) × (-3x + 4)

=》-2x - 9 - 27x + 36

=》<em>-29x + 27</em>

If there bill was 58.65 and they gave a sever a 15% tip, how much did they pay altogether
masha68 [24]

Answer:

<u>$67.43 altogether</u>

Step-by-step explanation:

A 15% percent tip means 15% OF the bill.

15% of 58.65

0.15*58.65=8.7975

You can't really pay $8.7975, so you would round to the nearest one hundredth which is $8.78.

Now you add the $8.78 to $58.65 which will give you $67.43.

I hope that helps!
