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.
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.
Answer:
The correct option is;
Segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A
Step-by-step explanation:
All chords perpendicular to the radius of a circle are bisected by the radius of the circle
Given that DA can be extended to the circumference of circle A to form a radius of the circle A, and that DA is perpendicular to EF, therefore, DA bisects EF or EF is bisected into two equal parts by DA such that segment ED is congruent to segment FD
Therefore, the correct option is that segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A.
