The

3

mile cab ride includes a basic charge as well as the cost for the distance covered.

For a

6

mile trip, the cost is

$

4.80

which means that :

The cost of

3

miles is

$

4.80

−

$

3.00

=

$

1.80

Therefore the cost for

1

mile is

$

1.80

÷

=

$

0.60

The basic fee for hiring the cab is  

$

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

[tex]8^0[/tex]

Applying exponent rule : [tex]x^0 =1[/tex]

[tex]8 ^0 \Longrightarrow 1[/tex]

[tex]\rule[225]{225}{2}[/tex]

Answer:

Step-by-step explanation:

3. [tex]\frac{3}{16}=\frac{x}{12}[/tex]

   36 = 16x

   9 = 4x

   x = [tex]\frac{9}{4}[/tex]

4. [tex]\frac{x}{120}=\frac{1}{24}[/tex]

   x = [tex]\frac{120}{24}[/tex]

   x = 5

5. [tex]\frac{a-2}{9}=\frac{2}{3}[/tex]

   3a - 6 = 18

   3a = 24

   a = 8

6. [tex]\frac{b+4}{5}=\frac{7}{4}[/tex]

  4b + 16 = 35

  4b = 19

   b = [tex]\frac{19}{4}[/tex]

7. [tex]\frac{3}{7}=\frac{c+4}{35}[/tex]

  105 = 7c + 28

  7c = 105 - 28

   7c = 77

   c = 11

8. [tex]\frac{2c}{11}=\frac{c-3}{4}[/tex]

   8c = 11c - 33

   11c - 8c = 33

    3c = 33

    c = 11

9. [tex]\frac{7}{k-2}=\frac{5}{8}[/tex]

   56 = 5k - 10

   5k = 66

    k = [tex]\frac{66}{5}[/tex]

12. [tex]\frac{c+1}{c-2}=\frac{4}{7}[/tex]

    7c + 7 = 4c - 8

    7c - 4c = -15

    3c = -15

    c = -5

13. [tex]\frac{v}{4}= \frac{7}{8}[/tex]

    v = [tex]\frac{7}{2}[/tex]

14. [tex]\frac{9}{14}=\frac{3}{n}[/tex]

    9n = 42

    n = [tex]\frac{42}{9}[/tex]

    n = [tex]\frac{14}{3}[/tex]

15. [tex]\frac{b+13}{2}=\frac{-5b}{3}[/tex]

   3b +39 = -10b

   13b = -39

    b = -3

16. [tex]\frac{3b}{b-4}=\frac{3}{7}[/tex]

    21b = 3b - 12

    21b - 3b = -12

    18b = -12

    b = -[tex]\frac{12}{18}[/tex]

    b = [tex]-\frac{2}{3}[/tex]

17. [tex]\frac{x+2}{2x-6}=\frac{3}{8}[/tex]

   8x + 16 = 6x - 18

   8x - 6x = -18 - 16

   2x = -34

    x = -17

Total cost = ($8.50b) + ($3.99d)

Step-by-step explanation:

In a bakery, the cost of a dozen bagels = $8.50

and the cost of a dozen donuts = $3.99

1 Dozen = 12 pieces

Let 'b' represents the number of bagels (in dozen) and d represents dozen donuts.

The expression that represents total cost of b dozen bagels and d dozen donuts would be :

Total cost = ($8.50b) + ($3.99d)

Answer:

Step-by-step explanation:

1. 12a = 4

    12a/12 = 4/12

    a = 1/3

2.  2c = 7(8/7)

    2c = 8

     c = 4

3. 5h = 6(-3/8)

    5h = -18/8

    5h = -9/4

    20h = -9

      h = -9/20

4. -27m = -4

    m = 4/27

5. -42p = 21

    p = -21/24 = -1/2

6. -7x = 4/7

    x = -4

7. 9n = -40/9

  n = -40

8. 15g = -24

  g = -24/15 = -8/5

9. 4s = 56

   s = 14

10 -5t = -9(2/3)

     -5t = -6

    t = 6/5

Answer:

4372 people would have been sick over time.

Step-by-step explanation:

Since the vaccine would be found in a week, then the over time is a week (7 days). Each day, a sick person infects two additional people.

Number of people infected by Velma can be predicted as follows:

Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458

Number of people infected by Velma = 1458 + 486 + 162 + 54 + 18 + 6 + 2

                                                       = 2186

Also, number of people infected by Stanley can be predicted as follows:

Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458

Number of people infected by Stanley = 1458 + 486 + 162 + 54 + 18 + 6 + 2

                                                       = 2186

Total number of people than can be infected over time = 2186 + 2186

                                                      = 4372

Therefore, the predictable number of infected people over time would be 4372. All citizens of Parsnipville would have been infected before the vaccine is available.

Answer:

-20 feet

Step-by-step explanation:

If the fish are closser to the suface it will be closer to 0 on the number line.

A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.

Given that,
A fish finder is an instrument on a boat that indicates where fish are located. The range of the fishfinder is to be specified.

Range, it is the set of the values that come out to an outcome for certain mathematical operations.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The range usual range of the fishfinder is standardly 0 to -20 on the number line of the instrument, where the negative sign indicates the depth.

Thus, A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.

I think it is done like this but I am not sure.

Simplifying

9 + -4(2x + -1) = 45

Reorder the terms:

9 + -4(-1 + 2x) = 45

9 + (-1 * -4 + 2x * -4) = 45

9 + (4 + -8x) = 45

Combine like terms: 9 + 4 = 13

13 + -8x = 45

Solving

13 + -8x = 45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13' to each side of the equation.

13 + -13 + -8x = 45 + -13

Combine like terms: 13 + -13 = 0

0 + -8x = 45 + -13

-8x = 45 + -13

Combine like terms: 45 + -13 = 32

-8x = 32

Divide each side by '-8'.

x = -4

Simplifying

x = -4

The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.

We have,

Distribute the -4 to the terms inside the parentheses:

9 - 4(2x - 1) = 45

9 - 8x + 4 = 45

Combine like terms:

13 - 8x = 45

Move the constant term to the other side of the equation by subtracting 13 from both sides:

13 - 8x - 13 = 45 - 13

-8x = 32

Divide both sides of the equation by -8 to isolate the variable:

(-8x) / (-8) = 32 / (-8)

x = -4

Therefore,

The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.
