Area of rectangle: b*h
12*5=60
10*5=50
(60*4)+(50*4)=440
The total surface area of the visible sides of the boxes would be 440 square inches.

Answer:
×
Step-by-step explanation:
×
as scientific notation is equal to ×
The variables are
- x = number of mini hot dogs.
- y = number of mozzarella sticks.
And the system of equations is:
x*60 + y*70 = 1080
x = y + 5
<h3>
How to write the system of equations?</h3>
First, we need to define the variables that we will use on our system.
- x = number of mini hot dogs.
- y = number of mozzarella sticks.
We know that each hot dog has 60 calories and each mozzarella stick has 70 calories, and the total number of calories is 1080, then the first equation of our system is:
x*60 + y*70 = 1080
We also know that there are 5 more mini hot dogs than mozzarella sticks, then the second equation is:
x = y + 5
Then the system of equations that models the given situation is:
x*60 + y*70 = 1080
x = y + 5

Answer:
$90
Step-by-step explanation:
First the given is the listed price of DVD which is 120 dollars.
Now we need to find out what the price will be after discount of 25%
To do this we will have to convert the percentage to decimal by moving decimal 2 place left and removing percentage sign which will become 0.25.
Then we multiply by the listed price which is 120
so 120*0.25=30
so we subtract 30 by original price cause that is the discount off we are receiving
120-30=90
so 90 will be the sale price after 25% discount.
