Answer:
sum of the interior angles x and y gives the exterior angle z
(4n-18)°+(n+8)°=(133-6n)°
4n°-18°+n°+8°=133°-6n°
4n°+n°-18°+8°=133°-6n°
5n°-10°=133°-6n°
5n°+6n°=133°+10°
11n°=143°
11°n/11°=143°/11°
n=13
exterior angle=133-6×13
=133-78
=55
Answer:
$32.80
Step-by-step explanation:
Find out how much Nancy spent on 4 violins and 2 song books.
1 violin = 87.82
4 violins = 87.82 x 4 = 351.28
1 song book = 7.96
2 song books = 7.96 x 2 = 15.92
351.28 + 15.92 = 367.20
4 x 100 dollar bills = 400 dollars
Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.
400 - 367.20 = 32.80
If Quinn is included in the 35 friends the answer would be 35x126=4410.
-2x + 6 - 13x + 16
= -15x + 22
