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:
14, 20, 0, 0, 0
Step-by-step explanation:
The notation indicates the absolute value of x, therefore it can be rewritten as:
if x 0
if x < 0
In this problem, we have the expression
Therefore, we can rewrite it as:
if x ≥ 0:
(a)
If x < 0:
(b)
So now we can substitute the given values into the two expressions:
x = 7 (positive value, so we use expression (a):
x = 10 (positive values, so we use expression (a):
x = 0 (zero, so we can use expression (a):
x = -3 (negative value, so we use expression (b):
x = -8 (negative value, so we use expression (b):
