Answer:
3 hours
Step-by-step explanation:
D=4H+35
47=4H+35
47-35=4H
12=4H
H=3
Answer:
C) 6
Step-by-step explanation:
From the given data we can find the constant of proportionality by dividing The number of people by number of cars.
Constant of proportionality = 
Taking any point from the table will give the same constant of proportionality as they are proportional quantities.
Constant of proportionality = 
This can be written as 6 people per car.
For 10 cars, number of people will be =
=60 people.
Answer:
33% off is the better deal
Step-by-step explanation:
1.33 times as much popcorn for the same price is equivalent to 1/1.33 ≈ 0.75 times the price for the original amount of popcorn. That price is equivalent to a sale of 1 - 0.75 = 0.25 = 25% off.
The sale price of 33% off is a better deal (if you don't want the extra popcorn).
Answer:

Step-by-step explanation:
Using FOIL (First, outer, inner, last)
First, we multiply 3x and x to get
(First)
We then multiply 3x and 1 to get
(outer)
Then 4 and x to get
(Inner)
Then multiply 1 and 4 to get
(last)
Since the quadratics are all positive, we add all the terms together to get:
. Since 3x and 4x are like terms, we add them together and simplify to get:

And since we can't simplify any further, that's our answer!
Hope this helps :D
