Brie bought a movie pass for $ 40, let c be the cost of a movie. brie has seen 5 movies, the amount left on her pass is equal to the amount her friend spent to see 3 movies

The cost of each movie is $ 5

Step-by-step explanation:

The value of movie pass = $ 40

The number of movies seen by Brie = 5

The number of movie seen by her friend = 3

Let the cost of movie = c

So , According to question :

   The amount left on pass = amount spend by friend on 3 movies

I.e  $ 40 - 5 c  =  3 c

Or  5 c + 3 c = $ 40

Or,   8 c = $ 40

So ,   c = = 5

Hence The cost of each movie is $ 5     Answer

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
