2.) Helen is considering two different moving services. Service A charges a $15 monthly fee for unlimited streaming of movies and $2.50 per DVD rental. Service B charges a $12 monthly fee for unlimited streaming of movies and $3.50 per DVD rental. The system of equations below describes the relationship between the number of DVDs rented per month (x) and the monthly cost (y), in dollars for both services.
y = 15.00 + 2.50x AND y = 12.00 + 3.50x Which statement about the costs of the movie services is true?
A. When Helen rents fewer than 3 DVD's per month, service A will cost less per month than service B will cost.
B. When Helen rents more than 3 DVDs per month, service B will $12 more per month than service A will cost.
C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month. D. When Helen rents 6 DVDs per month, either service will cost her $27.00 per month.

Answers

Answer 1

Answer:

C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.

Step-by-step explanation:

y = 15.00 + 2.50x

y = 12.00 + 3.50x

When x = 2

y = 15.00 + 2.50x

= 15.00 + 2.50(2)

= 15.00 + 5.00

= 20.000

y = 12.00 + 3.50x

= 12.00 + 3.50(2)

= 12.00 + 7.00

= 20.00

When x= 4

y = 15.00 + 2.50x

=15.00 + 2.50(4)

= 15.00 + 10.00

= 25.00

y = 12.00 + 3.50x

= 12.00 + 3.50(4)

= 12.00 + 14.00

=26.00

When x = 3

y = 15.00 + 2.50x

= 15.00 + 2.50(3)

= 15.00 + 7.50

= 22.50

y = 12.00 + 3.50x

= 12.00 + 3.50(3)

= 12.00 + 10.50

= 22.50

When x = 6

y = 15.00 + 2.50x

= 15.00 + 2.50(6)

= 15.00 + 15.00

= 30.00

y = 12.00 + 3.50x

= 12.00 + 3.50(6)

=12.00 + 21.00

= 33.00

The correct answer:

C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.

Step-by-step explanation:

This how you but this decimals and fractions from least to greatest. I hope this helps

First, you want to get all you options to be decimals.
146/25 is 5.84. 5 17/20 as an improper fraction is 117/20 because 20 times 5 is 100 and then add 17. 117/20 is 5.85.

In order from least to greatest would be 5.275, 146/25, 5 17/20, and then 6.27

Task: You and your friend were taking turns rolling a die when you thought of a game: If a one is rolled by either player, you pay your friend 50 cents, but when a different number is rolled, your friend pays you 10 cents. After 30 rolls, it turned out that you were even, and neither of you won anything.

Step-by-step explanation:

\_( XD)_/

Answer:

6 times

Step-by-step explanation:

'one' 50 cents, other 10 cents

If you get 50 cents you have to roll other number 5 times to minus 50 cents (50 divided by 10 is 5)

because they got nothing after roll so if they get a cents they have to minus it rolling other number

So if you divide 30 (the number of rolling) by 5 (the number of times to minus 50 cents) so the answer will be 6

Step-by-step explanation:

equation: y = x - 6 + x^2

(6,0) (7,1) (8,4) (9,9)

I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER

Answers

Answer:

[tex]xy=wz[/tex]

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = [tex]y[/tex] km/min

Time taken up the hill = [tex]x[/tex] minutes

Speed of Wilmer down the hill = [tex]z[/tex] km/min

Time taken up the hill = [tex]w[/tex] minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

[tex]Distance = Speed \times Time[/tex]

Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]

Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

[tex]xy=wz[/tex]

5x + 55= 2x+ 100
Please answer.

Answers

Answer:

x = 15

Step-by-step explanation:

Given

5x + 55 = 2x + 100 ( subtract 2x from, both sides )

3x + 55 = 100 ( subtract 55 from both sides )

3x = 45 ( divide both sides by 3 )

x = 15

X=15
Subtract 2x from Both sides and subtract 55 from both sides so that’ll be 3x=45 divide both sides by 3 and get 15

Sue makes bracelets. She uses

inches of chain to make one bracelet. How many bracelets can she make from a chain that is
49
1
2
inches long?

Answers

9514 1404 393

Answer:

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

(49 1/2)/(8 1/4) = (99/2)/(33/4)

= (99/2)(4/33) = (99/33)(4/2)

= (3)(2) = 6

Answer:

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

(49 1/2)/(8 1/4) = (99/2)/(33/4)

= (99/2)(4/33) = (99/33)(4/2)

= (3)(2) = 6
