Answer:

Quarters = 20

Dimes = 14

Step-by-step explanation:

Dime = x = 10 cent = $0.1

Quarter = y = 25 cent = $0.25

x + y = 34 - - - (1)

0.1x + 0.25y = 6.40 - - - - (2)

From (1)

x = 34 - y

0.1(34 - y) + 0.25y = 6.40

3.4 - 0.1y + 0.25y = 6.40

3.4 + 0.15y = 6.40

0.15y = 6.40 - 3.40

0.15y = 3

y = 3 / 0.15

y = 20

x = 34 - y

x = 34 - 20

x = 14

Quarters = 20

Dimes = 14

Answer:

-8

Step-by-step explanation:

10 -2b^2

Let b=-3

10 - 2( -3)^2

Do the exponent first

10 -2(9)

Multiply

10 -18

Subtract

-8

Answer:

- 8

Step-by-step explanation:

Given

10 - 2b² ← substitute b = - 3 into the expression

= 10 - 2(- 3)²

= 10 - 2(9)

= 10 - 18

= - 8

Answer:

A = 101 degrees         d = 97 degrees

Step-by-step explanation:

180 - 79 = 101    as angles in a straight line = 180

101 + 79 + 83 = 263

360 - 263 = 97 degrees

Step-by-step explanation:

∠2 ≅ ∠4

Answer:

1. x = 21°

2. x = 30°

3. x = 7°

5 x = 3

Step-by-step explanation:

Solving for x

1. 15+ 5x + 60° = 180°

75 + 5x = 180°

5x = 180 - 75

5x = 105

x = 105/5

x = 21°

2. These angle are vertical angles

Hence:

13x - 5 = 125°

13x = 125° + 5

13x = 130

x = 130/3

x = 30°

3. 8x - 1 = 55°

8x = 55 + 1

8x = 56

x = 56/8

x = 7°

5. These angles are angles in a straight line

17x - 1 + 130° = 180°

17x + 129° = 180°

17x = 180° - 129°

17x = 51

x = 51/17

x = 3°

Answer:

B. 6 sides

Step-by-step explanation:

Interior angles of a n side Regular Polygon = (180n – 360) / n

120 = (180n – 360) / n

120n =180n - 360

180n - 120n = 360

60n = 360

n = 6

check: sum of interior angles of 6 side polygon: 180 * (6-2) = 720

720/6 = 120

Answer:

(x , y) ----> (-x , y)

Step-by-step explanation:

(x , y) ----> (-x , y)

Example for 1. :

(-4,2) ---> (4,2)

Answer:

-1/6

Step-by-step explanation:

To get the slope we need the equation in the form y=mx+c, and m is the slope.

2x+12y=192

12y = -2x + 192

y = -2/12 x + 16

-2/12 is the slope but this can be simplified to -1/6

Answer:

The 2 numbers = 81 and 83

Step-by-step explanation:

As, one number = x

The other, because it's an even number and consecutive = x + 2

So the larger numbef here is x + 2

And they are saying 3 times x + 2 plus x = 330

So let's solve!

3 times x + 2 = 3(x+2) = 3x + 6

So we will add it to x = (3x + 6) +(x) = 4x + 6

So they are saying the sum of them will be 330

So, 4x + 6 = 330

4x = 330 - 6

4x = 324

x = 324/4

x = 81

So x is the first number = 81

And the second is x + 2 = 81 + 2 = 83

So the 2 numbers are 81, 83

Lets check!

3 times the bigger number = 83 x 3 = 249

We will add it to 81 and we will get 330

So, 249 + 81 = 330

So the answer is right

Answer:

b

Step-by-step explanation:

if you say 1<2 and multiply both by negative 3 you will have -3 > -6

Answer:

Step-by-step explanation:

When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number. You can also consider this with a number line.

Answer:

Answer:

The process is the same. They just have different symbols.

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

A). From the graph attached,

    Arrow AB represents the RISE and arrow BC represents the RUN.

B). RUN from point A to B (Horizontal distance) = 2 units

    Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]

    Slope of the line segment AB = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                                                       = [tex]\frac{-4}{2}[/tex]

                                                       = -2

   Therefore, slope of the line = slope of the line segment AB = -2

    Option D will be the correct option.
