12. Two trains, Train A and Train B, weigh a total of 312 tons. Train A is heavier than Train B. The difference in their weights is 170 tons. Use elimination to solve the system of equations to find the weight of each train. a + b = 312 a-b= 170 a + b = 312 a - b = 170​

Answers

Answer:

a = 241

b = 71

Step-by-step explanation:

a + b = 312 (#1)

a - b = 170 (#2)

(#1) + (#2) = 2a = 482.

a = 482 / 2 = 241.

b = 312 - 241 = 71.

HELP PLEASE FAST 15 and 16 how to solve PLEASE

Answers

Answer:

15. 6

16. 40

Step-by-step explanation:

Use the formula for pythagorus: c^2 = a^2 + b^2

15. 10^2 = 8^2 + b^2

100 = 64 + b^2

*minus 64 on both sides

36 = b^2

*square root both sides

b = √36 = 6  

16. c^2 = 24^2 + 32^2

c^2 = 576 + 1024

c^2 = 1600

*square root both sides

c = √1600 = 40

Hope this helps :)

1) 164

2) 1600

because a^2 + b^2 = c^2 <3

Lewis wants to play several games of paintball with his friends. At the park, it costs $10.90 for admission and paintballs, and $6.18 for each game he plays. Which of the following equations could be used to determine Lewis's total cost for several games of paintball? (Let x represent the number of games Lewis plays and y represent his total cost.) A. y = $10.90x + $6.18 B. y = $6.18x C. y = $6.18x + $10.90 D. $10.90y = $6.18x

Answers

Answer:

C. y= 6.18x + 10.9

Step-by-step explanation:

Every game that he plays (x) costs 6.18, for example, if he plays 3 games it would be 6.18 times 3 (games)

Now you have to add your admission, 10.9

To enter he needs to pay the admission ( 10.9 ) and also each game ( x ) he plays ( 6.18 )

Answers

-3x = 21
Divide -3 from both sides and you get x = -7

1/3x = 6
Divide 1/3 from both sides and you get x = 18

-1/2x = -7
Divide -1/2 from both sides and you get x = 14 (you get a positive answer from 2 negatives)

Dividing 1/3 is just multiplying by 3, and dividing -1/2 is just multiplying by -2

Answers

Answer:

Determine the proportion of months where memberships sold decreases,

increases and remained the same.

Step-by-step explanation:

I just took the test and got it correct.

The first step needed to simulate this data is:

Assign each month a digit from 1 to 24 to account for the 24 total months being compared.

Option B is the correct answer.

What is simulating data?

Simulating data means creating artificial data that mimics the characteristics of real data.

This artificial data is generated by using a model or a set of rules that describe how the data might be generated under certain conditions.

We have,

The first step needed to simulate this data is to assign each month a digit from 1 to 24 to account for the 24 total months being compared.

This will allow for an easy comparison of the sales data from last year and this year.

Once each month has been assigned a digit, the data can be organized and analyzed to determine the proportion of months where memberships sold decreased, increased, and remained the same, as well as the mean monthly sales from last year and this year.

Finally, random digits can be assigned to each sales figure from last year and this year to create a simulated data set that can be used for further analysis and modeling.

Thus,

The first step needed to simulate this data is:

Assign each month a digit from 1 to 24 to account for the 24 total months being compared.
