Answer:
option B
Step-by-step explanation:
Sum of interior angles of a polygon with n sides:
![[ \ because \ straight \ line \ angle = 180^\circ \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20because%20%5C%20straight%20%5C%20line%20%5C%20angle%20%3D%20180%5E%5Ccirc%20%5C%20%5D)
That is ,
OR
Sum of exterior angles of a regular polygon = 360
Given 1 exterior angle of the regular polygon is 40
Therefore ,
Answer:
Your answer should be $29.40
Step-by-step explanation:
If you divide 21 by 5 you get 4.2, so each book costs $4.20.
4.2 x 7 = 29.4
Therefore, your total cost for 7 books will be $29.40
I hope this helps!
y = 1.4x - 4.8
the equation of a line in ' slope - intercept form ' is
y = mx + c ( m is the slope and c the y- intercept )
the partial equation is y = 1.4x + c
to find c, substitute (2, - 2) into the partial equation
- 2 = 2.8 + c ⇒ c = - 2 - 2.8 = - 4.8
y = 1.4x - 4.8 is the equation in slope- intercept form
Answer:
A
Step-by-step explanation:
Its A because -4 - 3x > 7 because -1 - 7 is -6 but u have to - 1 because of the negative signs
No they are not equivalent and if you are trying to get a mixed number try dividing
