76, 84, 93, 67, 82, 87, and 76. what is the mean

Answer:

p = - 115

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

px - 5y = 60 ( subtract px from both sides )

- 5y = - px + 60 ( divide all terms by - 5 )

y = [tex]\frac{1}{5}[/tex] px - 12 ← in slope- intercept form

with slope m = [tex]\frac{1}{5}[/tex] p , thus

[tex]\frac{1}{5}[/tex] p = - 23 ( multiply both sides by 5 to clear the fraction )

p = - 115

Hey there! I'm happy to help!

First, let's see how many times 6 minutes fits into 20 minutes.

20/6=3 1/3

So, we are traveling 10 miles 3 1/3 times!

10×3 1/3=33 1/3

This train will travel 33 1/3 miles in 20 minutes.

Have a wonderful day! :D

Answer:

(-8.5,9)

Step-by-step explanation:

((-8+(-9))/2=-8.5

(7+11)/2=9

(-8.5,9)

Answer:

(-8.5, 9)

Step-by-step explanation:

use midpoint formula

(-8 + -9) ÷2 , (7 + 11) ÷ 2

-17 ÷ 2 , 18 ÷ 2

-8.5 , 9

so the coordinates of the midpoint are (-8.5, 9)

(not sure if that's how kilometers per hour is written, I am used to miles per hour.)

3s - 8 = 2s

First, let's subtract 3s from both sides

-8 = -s

Divide both sides by -1

8 = s

You have one solution which is s = 8

There is only a solution for the given equation 3s − 8 = 2s, s=8.

A mathematical equation is a claim that two expressions, which may contain variables or numbers, are equal. Equations are essential questions, and the main motivations for the development of mathematics have been efforts to methodically find answers to these questions.

It is given that the equation is,3s − 8 = 2s.

In order to find the value of s we have to simplify the given equations by applying the arithmetic operations.

3s - 8 = 2s

3s-2s= +8

s=8

Thus, the number of the solution for the given equation will be 1.

Answer:

x = -3

Step-by-step explanation:

[tex]4-(x+1) =6[/tex]

Distribute the negative

[tex]4 - x - 1 = 6[/tex]

Combine like terms on Left Hand Side

[tex]- x + 3 = 6[/tex]

Substract 3 from both sides

[tex]-x = 3[/tex]

Divide both sides by -1 to get rid of the negative

∴ [tex]x = - 3[/tex]

Answer:

see explanation

Step-by-step explanation:

(1)

[tex]\frac{6}{2}[/tex] = [tex]\frac{4}{p}[/tex] ( cross- multiply )

6p = 8 ( divide both sides by 6 )

p = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]

(2)

[tex]\frac{n}{4}[/tex] = [tex]\frac{8}{7}[/tex] ( cross- multiply )

7n = 32 ( divide both sides by 7 )

n = [tex]\frac{32}{7}[/tex]

(3)

[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{4}[/tex] ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = [tex]\frac{20}{3}[/tex]

Answer:

No solution

Step-by-step explanation:

There are no values of  x  that make the equation true.

Answer: No solutions

==========================================

Explanation:

Start things off by subtracting 5 from both sides

|x-1|+5 = 2

|x-1|+5-5 = 2-5

|x-1| = -3

We cannot go any further after this point. The result of any absolute value is never negative. The absolute value represents distance from some number to 0. For example, saying |-7| = 7 means -7 is seven units away from 0 on a number line. Negative distance does not make sense.

So going back to |x-1| = -3 makes no sense as well. There are no numbers we can plug in for x to have |x-1| = -3 be true.

The equation |x-1| = -3 has no solutions, so the original equation doesn't have any solutions either.

Answer:

[tex] MP = 29 [/tex]

Step-by-step explanation:

Given:

[tex] MN = 17 [/tex]

[tex] NP = 3y [/tex]

[tex] MP = 5y + 9 [/tex]

[tex] MN + NP = MP [/tex] (segment addition postulate)

[tex] 17 + 3y = 5y + 9 [/tex] (substitution)

[tex] 3y = 5y + 9 - 17 [/tex] (subtracting 17 from each side)

[tex] 3y = 5y + 8 [/tex]

[tex] 3y - 5y = 5y - 8 - 5y [/tex] (Subtracting 5y from both sides)

[tex] -2y = 5y - 8 - 5y [/tex]

[tex] -2y = - 8 [/tex]

[tex] y = 4 [/tex] (dividing both sides by -2)

[tex] MP = 5y + 9 [/tex]

Plug in the value of y

[tex] MP = 5(4) + 9 = 20 + 9 [/tex]

[tex] MP = 29 [/tex]

Answer:

x = -13

Step-by-step explanation:

3(x+1) = 2(x-5)

3x + 3 = 2x - 10

3x - 2x = -10 - 3

x = -13

Answer:

x = -13

Step-by-step explanation:

To solve for x, we will have to get the equation in a form with x by itself on one side and a value on the right side.

3(x + 1) = 2(x - 5)

Distribute the 3 on the left side and the 5 on the right side.

3x + 3 = 2x - 10

Subtract 3 from both sides.

3x = 2x - 13

Subtract 2x from both sides.

x = -13

And now we have the answer of x = -13.

Answer:

x = 7 and y = 1

Step-by-step explanation:

Coordinates of Coffee shop = (12, 16)

Coordinates of Library = (16, 8)

School has been shifted to the new position so that distance of school is preserved from the coffee shop.

Coordinates of the new position of school = (15, 10)

Ratio in which distance between coffee shop and library is divided by the location of school is x : y.

If a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided into two parts by point (x, y) in the ratio of m : n,

x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

y = [tex]\frac{my_2+ny_1}{m+n}[/tex]

From the points given in the picture,

15 = [tex]\frac{16x+8y}{x+y}[/tex]

15x + 15y = 16x + 8y

15y - 8y = 16x - 15x

7y = x

[tex]\frac{x}{y}=\frac{7}{1}[/tex]

Therefore, x = 7 and y = 1 will be the answer.
