Kareem runs 8 miles in 84 minutes. At the same rate, how many minutes would he take to run 6 miles?

Answer:

The answer is D

Step-by-step explanation:

Start by subtracting 2x from both sides

-4y = -2x + 8

Divide both sides by -4

y = 1/2x - 2

or

y = one-half x minus 2

Answer:

y = -3/5x + 1

Step-by-step explanation:

We are given a point and the slope so all we need to solve for is the y-intercept and we can do that by using the slope intercept form formula [ y = mx + b ] where m = slope and  b = y-intercept.

4 = -5(-3/5) + b

4 = 3 + b

1 = b

With the information we know, we can input the values into the formula once again.

y = -3/5x + 1

(d).

Step-by-step explanation:

a)2/5a=4/a-1

By cross multiplication:

5a×4=2(a-1)

20a=2a-2

20a-2a=-2

18a=-2

a=-2/18

a=-1/9

b)7/2d-5=9/3d+4

By cross multiplication:

7(3d+4)=9(2d-5)

21d+28=18d-45

21d-18d=-45-28

3d=-73

d=-73/3

c)3/e+1 + 1/2e+1=0

3/e+1=-1/2e+1

By cross multiplication

3(2e+1)=-1(e+1)

6e+3=-e-1

6e+e=-1-3

7e=-4

e=-4/7

d)5/2f-5-4/7f+1=0

By cross multiplication

5/2f-5=4/7f+1

5(7f+1)=4(2f-5)

35f+5=8f-20

35f-8f=-20-5

27f=-25

f=-25/27

Bytes are used to represent the number of bits in a computer system. There are 1024n bytes in n kilobytes.

Using the following representation:

[tex]KB \to[/tex] Kilobyte

[tex]B \to[/tex] Bytes

1024 bytes in 1 kilobyte is represented as:

[tex]1024B = 1KB[/tex]

Let the number of bytes in n kilobytes be x.

So, we have:

[tex]x = n\ KB[/tex] and

[tex]1024B = 1KB[/tex]

Cross multiply

[tex]x \times 1KB = 1024B \times nKB[/tex]

Divide both sides by KB

[tex]x \times 1 = 1024B \times n[/tex]

[tex]x = 1024n\ B[/tex]

Remove the units for proper representation

[tex]x = 1024n[/tex]

Hence, there are 1024n bytes in n kilobytes

Answer:

The answer is 3: -1: 19

Step-by-step explanation:

I. f(x) is output x is input so

       If x = 0

       f(0) = 3 - 8(0)

       f(0) = 3

       If x = 1/2

        f(1/2) = 3 - 8(1/2)

                 = 3 - 4

        f(1/2) = -1

         If x = -2

         f(-2) = 3 - 8(-2)

                 = 3 - (-16)

                 = 3 + 16

          f(-2) = 19

Answer:

11/8 or 1 3/8 or 1.375

Step-by-step explanation:

From the information given by the question, we can form an equation:

Let us call the number 'n'

8 × n - 7 = 4

We then move the 7 to the other side, changing it from minus to plus:

8 × n = 4 + 7

So,

8 × n = 11

We divide both sides by 8, to leave n on one side of the equation.

n = 11/8

Therefore, n = 11/8 or 1 3/8 or 1.375

Answer:

Step-by-step explanation:

The actual areas is 1125 in²

A scale drawing can be described as a drawing of an original image that is reduced by a constant proportion to the original image.    

scale of the drawing = original dimensions / dimensions of the scale drawing

The scale used by Joseph = 2 cm : 5 inches

This can be simplified further by dividing by 2

1 cm : 2.5 inches

Based on the image, the dimensions of the grill are 10 cm x 18cm

The length of the actual grill = 18 x 2.5 = 45 inches

The width of the actual grill = 10 x 2.5 = 25 inches

Area of a rectangle = length x width

Area of the actual space for the grill = 25 x 45 = 1125 in²
