Answers

Answer:

c = 2.99m+ 6.85

Step-by-step explanation:

one time fee of 6.85

2.99 per movie rental

in other words you must pay 6.85

and 2.99 times the number of movies you watch

m = movies watched

c = cost

therefore

c = 2.99m+ 6.85

watching 13 movies at movie mania would mean that m (movies watched) would be 13

put that into the equation:

c = 6.85+ 2.99(13)

c =  6.85+ 38.87

c = 45.72

June was thinking of a number. June doubles it and gets an answer of 98.9. What was the original number?

Answers

Answer: 49.45

Step-by-step explanation:

From the information, we are informed that June was thinking of a number and then doubles it and gets and gets an answer of 98.9.

Let the number be represented by x.

Since she doubles it, thus implies that:

2x = 98.9

x = 98.9 / 2

x = 49.45

The number is 49.45

Answers

Answer:

It is a proportional relationship

Step-by-step explanation:

Here, we want to know if the relationship is proportional or not

Looking at the table, we can see that every value of x multiplied by 4 will

give y

In simpler terms;

y = 4x

Hence, we have established that there is a proportional relationship between the x and y values

You would move you positive 3 to the left side so (y) is by itself. So you would have 3x-8=y. Then substitute X=5. So 3(5)-8=y. 15-8=y. 7=y

Answer:

[tex]y=3x-8[/tex]

Step-by-step explanation:

First, you have to isolate y on one side of the equation.

Step 1) Add 5 to both sides (this will cancel out the (-5) on the left)

Step 2) Subtract 3x from both sides (this will cancel out the (3x) on the left)

Step 3) Subtract y from both sides

Step 4) In order to make the desired variable positive, change the sign of everything in the equation

The step shown above will yield the answer of [tex]y=3x-8[/tex]

Find the value of x that makes m|| n.


Answers

Answer:

[tex]\huge\boxed{x=23}[/tex]

Step-by-step explanation:

In order to find the value of x that makes m || n, we need to note something.

When two parallel lines are cut by a transversal, their angle measures will be the same.

Therefore, in order for m and n to be parallel, their two angles listed must be equivalent.

So, we can set these expression equal to each other and solve for x.

[tex]7x - 11 = 4x + 58[/tex] [tex]7x = 4x+ 69[/tex] [tex]3x = 69[/tex] [tex]x = 23[/tex]

Therefore, x=23.

Answers

Answer:

180 pages in 2 hours

225 pages in 150 minutes

210 pages in 2 hours 20 minutes

Step-by-step explanation:

135 pages : 90 minutes

= 135/90

= 3/2

= 3 : 2

180 pages : 2 hours

180 pages : 120 minutes

= 180/120

= 3/2

= 3:2

60 pages : 30 minutes

= 60/30

= 2/1

= 2:1

108 pages : 2 1/2 hours

108 pages : 180 minutes

= 108/180

= 18/30

= 3/5

= 3:5

150 pages : 1 hour

150 : 60

= 150/60

= 10/6

= 5/3

= 5:3

225 pages : 150 minutes

= 225/150

= 9/6

= 3/2

= 3:2

210 pages : 2 hours 20 minutes

210 pages : 140 minutes

= 210/140

= 3/2

= 3:2

order these from least to greatest

Add a restaurant the ratio of kids meals sold two adult meals sold was 5:4 if there were 20 kids meals sold what is the combined amount of kids and adult meals sold?

Answers

Answer: The combined amount of kids and adult meals sold = 36

Step-by-step explanation:

Let the number of kids meals sold = 5x and the number of adult meals = 4x

Since total kids meals sold = 20

Then, 5x= 20

⇒ x =4

Adult meals = 4(4) = 16

Combined meals sold  =  kids meals + Adult meals

= 20+ 16

= 36

Hence, the combined amount of kids and adult meals sold = 36

OB.
(x - 8) and (x + 3)
O C.
(X + 8) and (x + 3)
OD.
(x - 8) and (x-3)

Answers

Answer:

OD

Step-by-step explanation:

The zero x=8 will make the factor (x-8) = 0 and the zero x=3 will make the factor (x-3) = 0.

so it's (x-8) and (x-3)
