Answer: b = - a

Step-by-step explanation:

Given that b is located the same distance from 0 as another number a, but in opposite direction.

If b varies directly as a

Then,

b = - ka

Hence the opposite variation or relationship between a and b means they both carry opposite signs

Hence,

b = - a

The sum of the interior angles of a polygon with n sides is

180(n-2)

Since a pentagon has 5 sides, the sum of its interior angles is

180(5-2) = 180 \cdot 3 = 540

Since it is a regular pentagon, all sides and angles are the same, so one single angle measures

\dfrac{540}{5} = 108 degrees.

Mr. Santon bought 2.6 yards of fabric for $8.94 about how much was the cost per yard
Zanzabum
Since this question is asking for the unit rate of the cost per yard of fabric, think of this as a ratio and proportions question where 2.6:8.94 = 1:x (represents the cost per yard).
To solve, cross multiply to get 2.6x=8.94
Then, solve for x and you get about $3.44 per yard
