Answer:

36

Step-by-step explanation:

Answer:

No

There are infinitely many solutions to the system.

{36x+21y=24312x+7y=81

Multiply the second equation by 3.

3(12x+7y36x+21y=81)=243

Subtract this new equation from the first equation.

36x+21y−(36x+21y0+0=243=243)=0 true

There are infinitely many values of x and y are possible.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

Two school groups go to a roller skating rink.

One group pays $243 for 36 admissions and 21 skate rentals.

The other group pays $81 for 12 admissions and 7 skate rentals.

Let x represent the cost of admission and let y represent the cost of a skate rental.

We have a system of equations,

36x + 21y = 243   {equation 1}

12x + 7y = 81        {equation 2}

Simplifying equation 1 we get,

36x + 21y = 243  

Divide by 3,

12x + 7y = 81      

That means, there are infinitely many solutions possible.

Therefore, there are infinitely many solutions possible.

Answer:

By substracting 0.16 from 0.35, we get 0.19. This is also true when we subtract 0.35 from 0.54. Thus, 0.19 is what we are adding to each previous term to get the next one. When we add 0.19 to 0.54, we get 0.73, and when we add 0.19 to 0.73, we get 0.92. Therefore, the next two terms in the pattern are 0.73 and 0.92.

Step-by-step explanation:

Answer:

0.73 and 0.92

Step-by-step explanation:

The difference of the first 3 is 0.19 per step, so continuing that is 0.73 and then 0.92

Answer:

You can purchase 10 songs after buying 12 videos.

Step-by-step explanation:

Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.

Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.

Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.

Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band mechandise.

(2/3) / (1/5) = 10/3 = 3 1/3

Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.

This can be elaborate in such a way also.  

Let suppose the total profit is $30.

then the profit from the ticket sale = 2/3 of 30 = $20

and the profit from the band merchandise sales = 1/5 of 30 = $6

Now dividing 20 by 6, which gives 10/3. the same answer that were calculated above.

Answer:

The point on a graph where a line crosses the Y-axis (The vertical line)

Step-by-step explanation:

Answer:

y = 3x

Step-by-step explanation:

from the table slope or rate of change is

m = 6 - 0 / 2 - 0 = 6/2 = 3

m = 12 - 6 / 4 - 2 = 6/2 = 3

m = 18 - 12 / 6 - 4 = 6/2 = 3

so m = 3

y = mx + c

c is y intercept --> y value when x is 0

y = 0 = c

so line equation is y = 3x + 0

y = 3x

Answer:

B, or 3x.

Step-by-step explanation:

When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.

2 x 3 = 6

4 x 3 = 12

6 x 3 = 18

Therefore, your answer is 3x.

Answer:

Answer to A: Each pound of coffee costs $6.32 dollars. Answer to B: He could buy 0.16 pounds of coffee for $1 dollar.

Step-by-step explanation:

For A, we use division. He payed $18.96 dollars for 3 pounds for coffee.

18.96 / 3 = 6.32.

Each pound of coffee costs $6.32 dollars.

For B, we use division Again.

The amount of pounds he could buy for $1 dollar is 0.16 pounds of coffee.
