Answer:

Step-by-step explanation:

At first, let's add - 9 to both the sides. So,

Now, using the definition of absolute value, we can change the equation to..

By, subtracting 3 from both the sides,

Now, divide both the sides by 6,

We now have 2 values of x. They are...

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
Answer:
l= (P-2w)/2
Step-by-step explanation:
P = 2l + 2w
Subtractc 2w both sides
P-2w = 2l
Divide 2 both sides
(P-2w)/2 = l
