Answer:

x= -1,  y = 6,  z = 3

Step-by-step explanation:

let me solve it with Gaussian Elimination

Answer:

As coins, they are already in their simplest ratio, since 25 and 38 don't have any common factor to divide by. (1 doesn't really count...)

As money, you need to multiply the 25 nickels x 5 cents per nickel, which gives you 125 cents,

and 38 dimes x 10 cents per dime, which gives you 380 cents.

So your new ratio is 125:380, which you can simplify by dividing each by 5, which gives you

25:76

SO, as money the ratio in simplest terms is 25:76. As numbers of coins, it's 25:38

If you think about it, it makes sense because:

10 cents is twice as much as 5 cents, and

76 cents is twice as much as 38 cents.

Hope this helps!

Ten cents cost twice as much as five cents, and 38 cents are equivalent to twice as much as 76 cents.

Explain about the Ratio?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value

Since there is no

to divide 25 by and 38 by, they are already in their most basic ratio as coins. (1 is hardly significant...)

To convert the 25 nickels to money, multiply them by the nickel's value, which comes to 125 cents.

and 38 dimes multiplied by 10 cents each, giving you 380 cents.

By dividing each by 5, you can simplify your new ratio of 125:380 and get

25:76

Therefore, the ratio is 25:76 expressed simply as money. It is 25:38 in monetary terms.

It makes sense if you think about it since

Ten cents are twice as expensive as five cents, and

38 cents is double what 76 cents

Answer:

B. The slope is –400

Answer: -400

Step-by-step explanation:

Answer:

y = (5/2)x + 13/2

y = 3

y = -2x + 6

Step-by-step explanation:

The left part of the function which is a line sloping up to the right contains points (-3, -1) and (-1, 4) which can be read off the graph.

Since we have two points, we can find the equation.

You can use the slope formula given two points, but I will read it off the graph with rise and run.

Go from point (-3, -1) to point (-1, 4) by going up 5 (the rise) and going right 2 (the run).

slope = rise/run = 5/2

y = mx + b

y = (5/2)x + b

Use point (-1, 4) for x and y and solve for b.

4 = (5/2)(-1) + b

8/2 + 5/2 = b

b = 13/2

y = (5/2)x + 13/2

This is the first answer.

The middle part is a horizontal line in which every point has y-coordinate 3.

The equation is:

y = 3

This is the second answer.

The right part is the line that slopes down to the right. We can read two points easily. Use points (3, 0) and (2, 2).

Start at (3, 0). Go left 1 (run of -1) and up 2 (rise of 2). Now you are at point (2, 2).

slope = rise/run = 2/(-1) = -2

Now we find the y-intercept on the graph. After you get to (2, 2), keep moving with the same run and rise of the slope. Go left 1 and up 2 to point (1, 4). Go again left 1 and up 2 to (0, 6). Point (0, 6) is on the y-axis, so it is the y-intercept.

b = 6

y = mx + b

y = -2x + 6

This is the third answer.

Answer:

[tex]y = \frac{-5}{6} x + 2\frac{2}{3}[/tex]

Step-by-step explanation:

Use the Point-Slope formula...

(y - (-4)) = -5/6(x - 8)

Simplify

y + 4 = -5/6x + [tex]6\frac{2}{3}[/tex]

y = -5/6 + 2 2/3

Hello,

Correct Answer is 12/3

For angle theta, perpendicular side is AB=12 and hypotenuse side is BC=13.

The sine of angle is equal to the ratio of perpendicular side to the hypotenuse side. So, sine of angle theta is:-

[tex]sin \: θ = \frac{12}{3} [/tex]

So, sine ratio angle is 12/3.

{ Note: Here, the ratio is written using slash (/) symbol as it is asked to use the slash symbol in the answer. }

https://brainly.com/question/24983242 help

Step-by-step explanation:

12 + 4[5% - 4(x + 5)] = 7 - 5x

12 + 4•(5% - 4•(x + 5)) = 7 - 5•x

11x = -55

x = -5

Answer:

[tex]x = - \frac{34}{5} [/tex]

Step-by-step explanation:

12 + 4 (5% - 4(x + 5)) = 7 - 5x

12 + 4 (5/100 - 4x - 20) = 7 - 5x

12 + 4 (-399/20 - 4x) = 7 - 5x

12 - 399/5 - 16x = 7 - 5x

-399/5 - 16x = 7 - 5x

-16x + 5x = 7 + 339/5

-11x = 374/5

x = -34/5

Answer:

The correct answer is the first option.

Step-by-step explanation:

The correct function notation is f ( x ) = x because the slope is 1, and the y-intercept is 0.  The y-intercept is the point on the graph where it crosses the y-axis.  

Therefore, the correct answer is the first option. Brainly isn't allowing me to post the equation for some reason.

Answer:

  (a)  f(3) < g(3)

Step-by-step explanation:

Put the number where the variable is and do the arithmetic.

  f(3) = 4·3³ = 4·27 = 108

  g(3) = 3·4³ = 3·64 = 192

  108 < 192

  f(3) < g(3)

The options that are true include:

A. One pound of pistachios plus 1 pound of almonds cost $20.

C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.

E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.

Cost of almond = a

Cost of pistachios = a + 4

Therefore, based on the information given, the equation to solve the question will be:

2(a + 4) + 3a = 48

Collect like terms

2a + 8 + 3a = 48

5a = 48 - 8

5a = 40

a = 40/5

a = 8

Almonds cost $8

Pistachios cost $12

In conclusion, the correct options are A, C, and E.
