Alang must visit 8 times to the theatre to earn a free movie ticket.

<h3>What is an expression?</h3>

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Alang has a points card for a movie theatre. He receives 55 reward points just for signing up. He earns 3.5 points for each visit to the movie theatre. He needs 83 points for a free movie ticket.

Form an equation and calculate the number of tickets:-

55 + 3.5N = 83

3.5 N = 83 - 55

3.5N = 28

N = 28 / 3.5

N = 8

Therefore, Alang must visit 8 times to the theatre to earn a free movie ticket.

Find the value of x that makes m ∥ n .
Alla [95]

Answer:

60

Step-by-step explanation:

(2x+15)=135    They're corresponding angles so they equal/congruent

<u>      -15   -15</u>       Subtract 15 on both sides since you're looking for x

<u>2x</u> = <u> 120</u>       Bring down the remains and subtract 135 from 15

 2        2        Add 2 on both sides

x= 60            Divide.
