-8x +(-56)=16

Answers

Answer 1

Answer:

x = -9

-8x + -56 = 16

-8x - 56 = 16

-8x = 16 + 56

-8x = 72

x = 72/8

x= -9

Answer 2

Answer:

-9

Step-by-step explanation:

-8x + (-56) = 16

Take away -56 from both sides

-8x = 72

Divide both sides by -8

x = -9

Answer: A. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.

System A :

-x - 2y = 7 ..........(1)

5x - 6y = -3 ..........(2)

If we multiply the first equation by 5, then we will get :

5(- x - 2y) = 5(7)

⇒ - 5x - 10y = 35 ........... (3)

Now the Sum of equation (2) and equation (3) is:

⇒ Sum :  

Now if we replace the second equation in system A with this  , then we will get the system B.

Solution of system B:

First we will take the second equation as there is only one variable 'y'. So, we will solve that equation for 'y'

Now for solving 'x', we will plug y= -2 into the first equation

So, the solution of system B is (-3, -2), that means the solution of both systems are same.

Step-by-step explanation:

Answer: D:

To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.

The revenue from selling x tickets is r(x) = 10x. The cost for buying x tickets is c(x) = 8x + 40. The profit from selling x tickets is p(x) = r(x) – c(x).9. What is p(x)? *

Answers

Answer:

p(x)=2x-40

Step-by-step explanation:

Substitute the variables

p(x)=10x-(8x+40)

p(x)= 10x-8x-40

p(x)=2x-40

Answer:

p(X) = r(X) - c(X).9

⇔ p(X) = 10x - (8x+ 40).9

⇔ p(X) = 10x - 72x - 360

⇔ p(X) = -62x - 360

23.82600 round to three significant figures​

Answers

Answer:

23.8 i think

Step-by-step explanation:

Answer:

[tex]23.83[/tex]

Step-by-step explanation:

[tex]--------------------------------------------[/tex]

According to Maths3000, Rounding to 3 significant figures is probably the most common way of rounding off. Rounding the number off to 3 significant figures means you require 3 non-zero digits from the start of the number. So in example 1, 27.1258 gets rounded to 27.1 figures.[tex]--------------------------------------------[/tex]

It is 23.83 because rounding by three significant figures is picking three of the last numbers, and rounding the 4th number. In this case, 6 is more than 5, so 23.82 becomes 23.83

Answers

Answer:

The answer is c.29

Step-by-step explanation:

I used Google xD

Answer:

Largest number = 29

Step-by-step explanation:

Let the consecutive numbers by (x + 1) ; (x + 2) and (x +3)

x +1 + x + 2 + x + 3 = 84         {Combine like terms}

x + x +x + 1  + 2 + 3 = 84

               3x + 6 = 84

                    3x = 84 - 6

                     3x = 78

                        x = 78/3

x = 26

Largest number = x + 3 = 26 + 3

                           =29

Part III: Choose either of the methods described in parts I or II to solve the system of equations.
Write your answer as an ordered pair. Show your work. (3 points)

Answers

1) If the first equation is 2x-3y=21, To eliminate the x-terms, I would multiply the first equation by -3. To make -6x+9y+63.

Then, I would subtract the second row from the first row to make 7y=-70

Next, divide both sides by 7 to solve for y. y = -10.

2) To eliminate the y-terms, I would multiply the first equation by 2 and the second equation by -3. It will make 4x-6y=42 and 18x-6y=-21.

Now, subtract the two equations to make -14x=63.

Lastly, divide both sides of the equation by -14 to find x. x = -9/2

3) The answer as an ordered pair is (-9/2, -10).
