Answer:

Keith's rate in chapters per hour is 8.

Step-by-step explanation:

Divide his 48 chapters by the 6 hours he read and in total it will be a ratio of 8 chapters to one hour.

Keith's rate in chapters per hour will be 8.

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

We are given that Keith reads 48 chapters of a book in 6 hours.

Therefore,

We need to Divide his 48 chapters by the 6 hours he read

48/6

= 8

Hence, in total it will be a ratio of 8 chapters to one hour.

Step-by-step explanation:

Formular:

[tex]mean = \frac{ \sum(n_{1}, \: n _{2}, \: ...n_{n} ) }{n} \\ [/tex]

therefore:

[tex]140 = \frac{(120 + 145 + 130 + 80 + 95 + 100 + 340 + n)}{8} \\ \\ (8 \times 140) = 1010 + n \\ 1010 + n = 1120 \\ n = 1120 - 1010 \\ n = 110[/tex]

Answer:

5/4 or 1 1/4 cup of oil

Step-by-step explanation:

Let's make a ratio. 1/4:10. We need to multiply 10 by 5 to get 50 cookies and do the same on the other side of the ratio. 1/4x5=5/4 or 1 1/4 and 10x5 is 50. So our final ratio would be 5/4:50. Hope this helped.

Answer:

Answer: [tex]f^{-1}(x)=\frac{x+3}{2}[/tex]

Step-by-step explanation:

The inverse of an equation is when you switch the x-value with the y-value. The y-value is equal to f(x). So, your work will look something like this. Note the changes in bold.

f(x) = 2x - 3

f(x) = y

y = 2x - 3

x = 2y -3

x + 3 = 2y

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

y = [tex]\frac{x+3}{2}[/tex] (here, I'm just switching it so the y-value is on the left to make it easier to read)

y = f(x)

[tex]f^{-1}[/tex](x) is the notation for inverse f(x)

So, the final equation would be written as

[tex]f^{-1}(x)=\frac{x+3}{2}[/tex]

i hope it is helpful

The value of the given expression 5(2x + 6) for x = 4 will be 70.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

As per the given expression,

5(2x + 6)

Put x = 4

5(2x + 6) = 5(2(4) + 6)

⇒ 5(8 + 6) = 5 × 14 = 70

Hence "The value of the given expression 5(2x + 6) for x = 4 will be 70".

Answer:

(1, - 2 )

Step-by-step explanation:

Given the equations

9x + 2y = 5 ( subtract 9x from both sides )

2y = 5 - 9x ( divide terms by 2 )

y = 2.5 - 4.5x → (1)

7x - 3y = 13 → (2)

Substitute y = 2.5 - 4.5x into (2)

7x - 3(2.5 - 4.5x) = 13

7x - 7.5 + 13.5 = 13 , that is

7x + 6 = 13 ( subtract 6 from both sides )

7x = 7 ( divide both sides by 7 )

x = 1

Substitute x = 1 into (1) and evaluate for y

y = 2.5 - 4.5(1) = 2.5 - 4.5 = - 2

solution is (1, - 2 )

Answer:

JH = 15

Step-by-step explanation:

KJ = 10

KI = 14

IH = 11

JH = ?

In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:

JH = JI + 11

In order to find JI, we need to subtract KJ from KI. Here's the equation:

14(KI) - 10(KJ) = JI

14 - 10 = 4

JI = 4

Now we plug in the numbers from our first equation:

JH = JI + 11

JH = 4 + 11

JH = 15

Step-by-step explanation:

The question requires you to find the value of x given the expression and distance

The value of x = 26

Driver's first stoppage = 53 miles

Distance remaining = 41 miles

Total distance = Driver's first stoppage + Distance remaining

= 53 + 41

= 94 miles

Given expression:

3x + 16

If 3x + 16 = 94

Then,

3x = 94 - 16

3x = 78

x = 78 / 3

x = 26

The simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Length of the photo = 4 inches

Width of the photo = 8 inches

Since, frame around the photo is the same width all the way around.

Therefore, area of the frame of the photo = Length x width

⇒ area of the frame of the photo = 8x4 = 32 square inches

which is the required expression for the area of the frame of the photo.

Thus, the simplified expression for the area of the frame of the photo is 8x4 = 32 sq inches.
