Given:
Consider the below figure attached with this question.
To find:
The value of x.
Solution:
Angle sum property of a triangle: According to this property, the sum of all interior angles of a triangle is 180 degrees.
Using the angle sum property of triangle, we get




Therefore, the value of <em>x</em> is 30 degrees.
Answer:
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Step-by-step explanation:
We will write the equation to represent this scenario.
Let x be the number of people who went for movies.
Then the price of ticket for x people will be: 6.25x
They spent $12 on refreshments and a total of $30.75 so the equation will be:

solving the equation will give us total number of people
So,

Hence,
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
F(x) = sqrt(4-x)
You can get this by switching f(x) and x and then solving for f(x).
2/20 is equivalent to 1/10 because 2/2 is equal to 1 and 20/2 is equal to 10.
