If you are looking for an exact number it would be 1,736.17 but a rounded number would be 1,736. Reason for this is do 816/47=17.3617 then multiply by 100 to get 1,736.17.

Answer:

1,736.17021 miles

Step-by-step explanation:

you would get this by doing 100/47 which you would then multiply that number by the distance traveled so far which is 816 and then you would get the total distance.

Answers

Answer:

-0.5

Step-by-step explanation:

Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain how you found them.

Answers

To find those equations we can do any multiplication or division of both sides of the equation:

Examples:

2x + 9 = -15 | · 2

4x + 18 = -30

2x + 9 = -15 | · (-1)

-2x - 9 = 15

2x + 9 = -15 | ÷ 2

x + 4.5 = -7.5

There is the same solution: x = -12.

The three different equations (x = -12, 2x = -24, and -2x - 9 = 15) that have the same solution as the original equation 2x + 9 = -15.

To find three different equations that have the same solution as 2x + 9 = -15, we can manipulate the given equation using algebraic operations. The goal is to preserve the solution while changing the form of the equation. Here are three different equations:

Subtract 9 from both sides of the equation:

2x + 9 - 9 = -15 - 9

2x = -24

Divide both sides of the equation by 2:

(2x)/2 = (-24)/2

x = -12

This equation, x = -12, has the same solution as 2x + 9 = -15.

Multiply both sides of the equation by -1:

-1(2x + 9) = -1(-15)

-2x - 9 = 15

This equation, -2x - 9 = 15, has the same solution as 2x + 9 = -15.

By applying these transformations, we obtained three different equations (x = -12, 2x = -24, and -2x - 9 = 15) that have the same solution as the original equation 2x + 9 = -15.

Which system of equations is graphed below?

x-y=6, 4x+3y=1

x-y=6, 3x+4y=4

x+y=6, 4x-3y=3

x+y=6, 3x-4y=4

Answers

(Pls give brainliest! :D)

Answer:

Step-by-step explanation:

You know that the graph intercepts at the point of (4,-2)

Where x = 4 and y = -2.

This means that whenever you plug a value of x in the equation it should give the value of y.

For example when you plug x= 4 into the equation (B), it should look like this.

4- y = 6, solving for y gives us the value negative 2.

This means that it does give us this point, however, as the graph shows us, both lines meet at the point which means that both equation should give us this point.

If we substitute x = 4 in the second equation of b, we should be able to get 3(4) + 4y = 4. Solving for y gives us -2.

Hope this helps!
