It will be B. 6^6 because for 6^9 / 6^3, you subtract the exponents together when you divide exponents (9 - 3 = 6)
Answer:
$8.09
Step-by-step explanation:
To find the average you have to divide so 218.43/27 is 8.09
Answer:
EF is 4 units.
Step-by-step explanation:
It is given that the two triangles
are congruent to each other i.e.

Coordinates are given as:
A(-1,1)
B(2,4)
C(3,1)
As per the property of congruence, all the corresponding sides and angles of the two triangles are equal to each other.
i.e. AB = ED
BC = DF
AC = EF
We are given with the coordinates of points A, B and C here from which we can easily calculate the side AC using the distance formula.

Where
are the coordinates of the two points whose distance is to be calculated.
So,

Hence, <em>AC = EF = 4 units</em>
A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
