Answer:
You need to buy 12 books to get a $15 coupon.
Step-by-step explanation:
Giving the following information:
You get a $5 coupon for every 4 books you buy.
<u>First, we need to structure the total coupon formula:</u>
Total coupon= 5*x
x= pack of four books
<u>Now, for $15</u>
15 = 5x
15/5= x
3= x
4*3= 12
You need to buy 12 books to get a $15 coupon.
Answer
Haven't done this for a bit but I think it's 19
Step-by-step explanation:
2 * 2 * 2 = 8
27 - 8 = 19
Let smaller angle be x
Let larger angle be 20 + x
Sum of two supplementary angles = 180°
x + 20+ x = 180°
2x + 20 = 180
2x = 180-20 = 160
x = 160/2 = 80
Smaller angle = x = 80°
Larger angle = 20 + x = 20 + 80 = 100°
