A used automobile dealership recently reduced the price of a used compact car by 6%. If the price of the car before discount was $18 800, find the discount and the new price?

Step-by-step explanation:

5(r + 9) - 2(1 - r) = 1

5r + 45 - 2 + 2r = 1

7r + 43 = 1

7r = -42

r = -6.

Answer:

r = -6

Step-by-step explanation:

Given equation,

→ 5(r + 9) - 2(1 - r) = 1

Now the value of r will be,

→ 5(r + 9) - 2(1 - r) = 1

→ 5r + 45 - 2 + 2r = 1

→ 5r + 2r + 43 = 1

→ 7r = 1 - 43

→ 7r = -42

→ r = -42/7

→ [ r = -6 ]

Hence, the value of r is -6.

Answer:

22r-1

Step-by-step explanation:

5(2r+1)-3(-4r+2) Distribute the terms

10r+5+12r-6 Combine like terms

22r-1

Answer:

5 ×( 2r +1) - 3 × ( -4r +2)

= 10r +5 +12r -6

= 22r -1

Step-by-step explanation:

(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).

(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2

= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).

Answer:

t = [tex]\frac{s-5}{2}[/tex]

Step-by-step explanation:

Given

s = 2t + 5 ( subtract 5 from both sides )

s - 5 = 2t ( divide both sides by 2 )

[tex]\frac{s-5}{2}[/tex] = t

When you rewrite subtraction using the additive inverse, you add the opposite. That is, -5 becomes +(-5).

The appropriate choice is ...

... 4 + (−5) A horizontal number line is shown with labels from negative 8 to positive 8. A blue arrow begins at 0 and goes to 4. A red arrow begins at 4 and goes to negative 1.

Answer: 9

Step-by-step explanation: 3 is one half of the line and x-1 is the other. 2x-5 is the whole line so 3+x-1=2x-5 is our equation. Solve for x and you get 7. Then replace x with 7 in 2x-5 and you will get an answer of 9.

The numerical length of LN is 7 units.

It is required to determine the numerical length of LN.​

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

Given :

Point M is on line segment LN.

LM = 3

LN = 2x-5

MN = x-1

Use the Segment Addition Postulate:

L------------M--------------------------N

LM + MN = LN

3 + x-1 = 2x-5

2+5=2x-x

7=x

Hence, the numerical length of LN is 7 units.

Answer:

The greater than of -7 is 7. The less than -2 is 2.

Step-by-step explanation:

It's the same distance from both but, the positive number always been greater than negative number.

Both questions have an infinite number of correct answers.

Here are six numbers that are greater than -7:

-6.99999,  -4,  0,  3,  π,  4.00001

Here are six numbers that are less than -2:

-2.00001,  -3,  -π,  -4,  -136,  -201.358

p=1

Step-by-step explanation:

[tex]3p + 7 = - 4(4 - 6p) + 2 \\ 3p + 7 = - 16 + 24p + 2 \\ 3p - 24p = - 16 + 2 - 7 \\ - 21p = - 21[/tex]

[tex] \frac{ - 21p}{ - 21} = \frac{ - 21}{ - 21} \\ p = 1[/tex]

Answer:

p = 1

Step-by-step explanation:

Given

3p + 7 = - 4(4 - 6p) + 2 ← distribute and simplify right side

3p + 7 = - 16 + 24p + 2

3p + 7 = 24p - 14 ( subtract 3p from both sides )

7 = 21p - 14 ( add 14 to both sides )

21 = 21p ( divide both sides by 21 )

1 = p , that is p = 1

Answer:

Step-by-step explanation:

a line goes on forever but a segment does have two endpoints

Answer:

Step-by-step explanation:

1. y = 13x + 5

y = 13(0) + 5

y = 0 + 5

y = 5

(0,5)

y = 13(-2) + 5

y = -26 + 5

y = -21

(-2, -21)

2. y = -3x

y = -3(-3)

y = 9

y = -3(0)

y = 0

(0,0)

(-3,9)

3. y = x - 10

   y = -5 - 10

    y = -15

   (-5, -15)

  y = 8 - 10

   y = -2

   (8, -2)

The correct options are:

1. y = 13x + 5  ⇒ (0,5)

2. y = -3x ⇒ (0,0)

3. y = x - 10  ⇒ (8, -2)

Answer:

Interval width

Step-by-step explanation:

In normal statistics, we calculate range as difference between Maximum Value and Minimum Value of the data given.

However, in group simple frequency distribution, we have what we call interval width which is simply the range of values contained in each interval.

To determine this interval width, we we divide the observed range by the number of intervals chosen.

Answer:

adult tickets  6.9

children tickets  3.9

Step-by-step explanation:

3x + y = 24.60    L1

5x + 4y = 50.10  L2

5L1 - 3L2

15x +  5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9

40 = 5x + 30

40 - 30 = 5x

10 = 5x

x = 10/5

Answer:

The inequality that represents the second graph is:  [tex]x\leq3[/tex]

Step-by-step explanation:

From the second number line, you can see that the circle is closed on positive 3 and the arrow is pointing left - the direction of negative numbers, so you know that the value of x must be less than or equal to 3. Thus, you can write the inequality: [tex]x\leq3[/tex] - X is less than or equal to 3
