Answer:

  2y +3 = 4y +2

Step-by-step explanation:

The left side shows 2y +3.

The right side shows 4y +2.

The scale is shown in balance, so we must have ...

  2y +3 = 4y +2 . . . . equation from the model

__

The solution can be found by subtracting 2y+2 from both sides to leave ...

  1 = 2y

Then we can divide both sides by 2 to find what y stands for:

  1/2 = y . . . . solution to the equation

n) Using the given information, determine the medal category in which the United States far outperformed its closest competitor. Show your working to justify your answer.

Answers

The medal category in which the United States far outperformed its closest competitor is the gold medal category.

In order to determine which medal category the United States far outperformed its closest competitor, we need to determine the difference in the medals gotten by the United States and its closest competitor for each medal category. The medal category with the largest difference is the correct answer.

Gold medal

Medals US got = 1022

Medals the closest competitor had = Soviet Union = 440

Difference = 1022 - 440 = 582 medals.

Silver medals

Medals US got = 794

Medals the closest competitor had = Soviet Union = 357

Difference = 794 - 357 = 437 medals

Bronze medals

Medals US got = 704

Medals the closest competitor had = Germany = 349

Difference = 704 - 349 = 355 medals

But often I just need a rough answer, so I mentally convert this to 7,000 x 7,000 = 7 x 7 x 1,000 x 1,000 = 49,000,000. More formally I am converting the numbers the nearest approximation of the form k x 10n where k ∈ {the set of numbers for which I know times tables}. Then I use the times tables on the remaining significant digits and implicitly use the 10 times table to get the magnitude right. In this case the real answer is:

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The high temperature was recorded as 23 7°F = +23.7

the low temperature that same day was recorded as 6.9°F = -6.9 F

so,  difference between the high and low temperatures for that day

= 23.7- (-6.9)

= 30.6

Solve each system by elimination.

3) 3x + 4y = 12
-3x - y = 6

4) -5x – 6y = 5
-6x + 6y = 6

5) 7x - 4y = 19
10x - 2y = 16

6) 10x - 9y=-13
5x – 3y =-11

Answers

Answer:

3) x = -4 and y = 6

4) x = -1 and y = 0

5) x = 1 and y = -3

6) x = -4 and y = -3

Step-by-step explanation:

3) Add the equations:

(3x + 4y = 12) + (-3x - y = 6) (eliminate the x)

= 3y = 18

y = 18/3

y = 6

3x + 4(6) = 12

3x = 12 - 24

x = -12/3 = 4

4) Add the equations:

(-5x - 6y = 5) + (-6x + 6y = 6)

-11x = 11

x = -1

-5(-1) -6y = 5

-6y = 5 - 5

y = 0

5) 7x -4y = 19

10x - 2y = 16

Multiply the second equation by -2 to eliminate the y and add both equations.

-2(10x -2y = 16) =

(-20x + 4y = -32) + (7x - 4y = 19)

-13x = -13

x = 1

7(1) - 4y = 19

-4y = 19-7

y = 12/-4

y = 3

6) multiply the second equation by -2 to eliminate the x and then add the equations.

-2(5x - 3y = - 11) =

(-10x + 6y = 22) + (10x - 9y = - 13)

= -3y = 9

y = - 3

10x - 9(-3) = - 13

10x = -13 - 27

x = -40/10

x = -4

The cost for one ticket to a jazz concert is $7.50. Two tickets cost $15. Write an equation in point-slope form to represent the total cost y for x tickets.

Answers

An equation in the point-slope form to represent the total cost y for x tickets is [tex]y-15 = 2(x-2)\\[/tex]

Let the cost of ticket be C

Let the number of tickets be x

The coordinate for the cost of a ticket will be written as: (x, C)

If the cost for one ticket to a jazz concert is $7.50, this is represented in coordinate form as (1, 7.50)

If two tickets cost $15, his is represented in coordinate form as (2, 15)

Get the slope of the equation

[tex]m =\frac{15-7.5}{2-1}\\m=\frac{7.5}{1}\\m = 7.5\\[/tex]

Get the equation in point-slope form

[tex]y-y_1 = m(x-x_1)\\[/tex]

Substitute the slope and one of the point into the formula:

[tex]y-15 = 2(x-2)\\[/tex]

Hence an equation in the point-slope form to represent the total cost y for x tickets is [tex]y-15 = 2(x-2)\\[/tex]
