Step-by-step explanation:

4x - 48 = x there is the equation

Answer:

x = 48/5

Step-by-step explanation:

Let x = number, then:

[tex]48 - 4x = x[/tex]

By adding 4x on each side:

[tex] 48 - 4x + 4x = x + 4x[/tex], which is [tex] 48 = 5x [/tex]

Then, divide by 5 on both sides:

[tex]\frac{48}{5} = \frac{5x}{5}[/tex]

Simplifying x = 48 / 5

Answer:

The answer is 6.875 inches.

Step-by-step explanation:

After a snow storm, Michael measured [tex]6\frac{7}{8}[/tex] inches of snow.

We will convert this to improper fraction and then solve.

[tex]6\frac{7}{8}=\frac{55}{8}[/tex]

Now we can divide 55 by 8 to get decimal value.

This becomes 6.875 inches.

A function with direct variation is a linear function that passes through the origin (0, 0) and has a constant rate of change, the slope. Only the line passing through (negative 1, negative 4), (0, 0), and (1, 4) from the given options fulfills these conditions.

In Mathematics, a function with direct variation is a linear function that passes through the origin (0, 0).  It can be represented as the equation y = mx, where m is the slope of the line. The slope of the line determines if it is a direct variation. If it's a positive slope, y increases as x increases. If it's a negative slope, y decreases as x increases.

From the given options, only the coordinate plane with a line passing through (negative 1, negative 4), (0, 0), and (1, 4) represents a function with direct variation as it's a straight line passing through the origin.

To find the inverse function [tex]\( f^{-1}(x) \)[/tex]for the given function f(x) = -0.75x , you can follow these steps:

1. Start with the original function:

   f(x) = -0.75x

   y = -0.75x

3. Swap x and y to solve for x:

x = -0.75y

4. Solve for y:

  Divide both sides by -0.75:

[tex]\( y = \frac{x}{-0.75} )\\ \( y = -\frac{4}{3}x \)[/tex]

5. Replace y with [tex]\( f^{-1}(x) \)[/tex]:

[tex]\( f^{-1}(x) = -\frac{4}{3}x \)[/tex]

Final answer:

The response provides the inverse function of f(x) = -0.75x step-by-step.

Explanation:

Given: f(x) = -0.75x

To find the inverse function f-1(x):

Replace f(x) with y: y = -0.75x

Swap x and y: x = -0.75y

Solve for y: y = x/-0.75 = -4/3x

Therefore, f-1(x) = -4/3x

The speed of each planes are 375 mph and 415 mph.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

Let x be the speed of the slower plane, in mph.

Then, the speed of the other plane is x +40 mph.

Hence, The distance between two planes decreases at the rate;

⇒ x + (x+40)

⇒ 2x + 40 mph.

So, we can write equation as;

⇒ 3950 / (2x+40) =  5

⇒ 3950 = 10x + 200

⇒ 10x = 3750

⇒ x = 375

Thus, The speed of the slower plane = x

                                                         = 375  mph.

And, The speed of the other plane = x +40

                                                      = 375 + 40

                                                      = 415 mph.

Final answer:

To solve the problem, we use the concept of relative speed and set up an equation with the combined distance traveled by both planes. Solving the equation reveals that the speed of the slower plane is 375 mph and the faster plane is 440 mph.

Explanation:

The problem of two planes flying toward each other with a speed difference and meeting after a certain amount of time is a typical algebra question in relative speed and motion. We can let the slower plane's speed be x mph and the faster plane's speed be x + 65 mph. Since they meet after 3 hours and are 2445 miles apart, the sum of their distances traveled will equal 2445 miles.

Using the equation d = rt, where d denotes distance, r the rate, and t the time, we set up two expressions for the distances each plane travels:

We then add these expressions and set the sum equal to the total distance:

3x + 3(x + 65) = 2445

Solving for x, we get:

6x + 195 = 2445

6x = 2445 - 195

6x = 2250

x = 375

Therefore, the speed of the slower plane is 375 mph and the speed of the faster plane is 375 + 65 = 440 mph.

Answer:

the numbers are 3 and 5

Step-by-step explanation:

x = first number

y = second number

a.        x+2 = y

b.        x^2 + y^2 = 34

Replace y from equation a into equation b:

x^2 + (x+2)^2 = 34

Expand it

x^2 + x^2 + 4x + 4 = 34

2*x^2 + 4x = 30

2x^2 + 4x - 30=0

solving x:

x = -5 and x =3 , it says it is a positive number, then it is x is 3

and the second number, y = x + 2

y = 5

Lets test it!

Answer:

Step-by-step explanation:50,897 is in standard form.

Expanded form is adding all your place values which is 50,000+800+90+7. There was a 0 in the thousand place so you do not add anything for that place value.

So (5×10,000) + (8×100) +(9×10)+(7×1) which is each number times it place value then add them all up.

Answer:

The answer is 4.5

Step-by-step explanation:

Solve for a:

3a +11 > 5

Subtract 11 from both sides:

3a >-6

Divide both sides by 3:

a > -6/3

a > -2

The Correct graph is the second one, because it has the dot on the -2 and the arrow points to the right

The 2 number line shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

The image shows two number lines, and asks which one shows the solutions to the inequality 3a + 11 > 5.

To solve this inequality, we can subtract 11 from both sides, and then divide both sides by 3. This gives us a simpler inequality: a > -2.

This means that all values of a that are greater than -2 are solutions to the inequality. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.

The number line on the left of the image shows exactly this. Therefore, the number line on the left shows the solutions to the inequality 3a + 11 > 5.

The number line on the right of the image does not show the solutions to the inequality correctly. The open circle at -2 is missing, and the arrow points to the left, which is incorrect, since the solutions to the inequality are all values of a that are greater than -2, not less than -2.

Here is a more detailed explanation of the steps involved in solving the inequality:

1. Subtract 11 from both sides:

3a + 11 > 5

-11 - 11

3a > -6

2. Divide both sides by 3:

3a > -6

3 / 3

a > -6 / 3

3. Simplify:

a > -2

Therefore, the solution to the inequality is a > -2. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.

The number line on the left of the image shows exactly this. Therefore, the 2 number line on the left shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

Final answer:

The volume of the earth is approximately 1.0839 x 10¹⁵ cubic miles.

Explanation:

To find the volume of the earth, we can use the formula for the volume of a sphere: V = (4/3)πr³. Since we are given the diameter of the earth, we can calculate the radius by dividing the diameter by 2. In this case, the diameter is 7917.5 miles, so the radius is 3958.75 miles. Now, we can substitute the radius into the formula to find the volume:

V = (4/3)π(3958.75 miles)³

V ≈ 1.0839 x 10¹⁵ cubic miles.

Answer:

each book costs $13

Step-by-step explanation:

Let the cost of each book be $x

cost of buying 8 books = $8x

It is given that with an original amount of $116, after buying 8 books, he had $12 left over. Hence,

$8x + $12 = $116   (dropping the $ signs)

8x + 12 = 116

8x = 116 - 12

8x = 104

x = 13  (each book costs $13)

Answer:

he possibly spent $13 on order to end up with $12 left.

Step-by-step explanation:

1) look. at the number 116 you can use a calculator.

2) if 14 only leaves you with nothing you take it away

3) add 13 + 8X that should give you 104
