Answer:
$259.2
Step-by-step explanation:
<h3>How many square feet of carpet should she order?</h3>
<h3>She needs to buy 9×12 feet of Carpet</h3>
42 = -6 + 3x
42 = 3x - 6 (just moving 3x and -6 around)
42+ 6 = 3x - 6 + 6 (adding 6 to both sides)
42 = 3x
42/3 = 3x/3 (dividing by 3 to both sides to isolate for x)
14 = x
You're trying to isolate for x, so you have to get it alone on one side. To do this you have to add/subtract and multiply/divide, but remember that whatever you do to one side you have to do to the other. Hope this helped! :)
Answer:
9 comedy
12 horror
Step-by-step explanation:
First, there are 360 degrees in a circle.
Comedy = 90 degrees
Action and romance = 90 degrees combined
Horror = 120 degree
Science fiction = 60 degrees
To find sci fi : 90 +90 +120 = 300 - 360 = 60 degrees
36 students took the survey.
1/4 × 36 = 9
Horror is 120 degrees out of 360 degrees or 1/3 of the circle.
1/3 × 36 = 12
