Answer:
7d-5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length.
The perimeter of a regular pentagon is given by
P = 5s where s is the side length
35d -25 = 5s
Divide each side by 5
(35d-25)/5 = 5s/5
7d-5 =s
Each one of the sides is equal to 7d-5
Answer:
Step-by-step explanation:
Answer: The Mean Absolute Deviation (MAD) is 2.5.
Step-by-step explanation:
Answer:
The expressions are not equivalent.
Step-by-step explanation:
Three-tenths of the total volume, v =
= 0.3 × v --- (1)
But, 310x is 310 × v --- (2)
Since (1) and (2) represent the same volume,
0.3 × v = 310 × v
Divide both sides by v,
0.3 = 310 which is a contradiction.
Therefore, the expressions are not equivalent.
Answer: x = 4
Step-by-step explanation:
4x = 13 + 3
4x = 16
x = 16/4
x = 4
