A DVD store charges $4.70 for each day, a DVD is rented. The store also gives you a dollar off if the DVD is returned before 5 days. a.Write a rule to represent the rental charges. b. How much will you pay if you return the DVD after 4 days? 7 days?

Answers

Answer 1

Answer:

Answer:

For four days it would be $19.8. For seven days it would be $24.9

Step-by-step explanation:

4 days:

$4.70 x 4 + 1= 19.8

7 days:

$4.70 x 7 = $24.9

I took away 1 from the 4 day equation because the question said you get a dollar off if you return the dvd before 5 days.

Hope this helps!

If a movie starts at 7:00 and runs for a 108 minutes what time does it end

Answers

108 minutes gives us 1 hour and 48 minutes.
Adding this to the starting times gives us the answer
i.e 8.48 am/pm

Final answer:

The movie will end at 8:48 PM.

Explanation:

The movie starts at 7:00 and runs for 108 minutes. To find the end time, we add the duration of the movie to the starting time. Since 108 minutes is equal to 1 hour and 48 minutes, the movie will end at 8:48 PM.

15x+12=45+4x
whats x?

Answers

15x+12=45+4x ⇒15x - 4x = 45 - 12 ⇒ 11x = 33 ⇒ x = 3

Like terms are when the variable you have are the same. In this case it is x. Therefore, when you have like terms, you should add, or subtract your like terms.

(note: When you move one thing to the other side of the equation, make sure to do the opposite of the sign. i.e. if it is +4 when you move to the other side it will be -4).

15x+12=45+4x
15x+12-12=45+4x-12
15x=45+4x-12
15x-4x=45+4x-4x-12
15x-4x=45-12
11x = 33
this is the same as:
11*x = 33
the opposite of multiply is divide so when we move the 11 it has to be divide
11/11*x=33/11
x=3

Which inequality is equivalent to -x < -1

Answers

Answer:

x > 1

Step-by-step explanation:

To find an equivalent inequality for -x < -1, you can multiply both sides of the inequality by -1. When you multiply or divide both sides of an inequality by a negative number, you need to reverse the direction of the inequality sign. Here's how it works:

Starting inequality: -x < -1

Now, multiply both sides by -1 (remember to reverse the inequality sign):

-x * (-1) > -1 * (-1)

This simplifies to:

x > 1

So, the equivalent inequality is:

x > 1
