To find the value of x, we can multiply both sides of the equation x/8 = 200 by 8:
(x/8) * 8 = 200 * 8
x = 1600
Therefore, the value of x is 1600.
What is the value of x when x/8 = 200?

Choose the equation that could be used to solve this problem.
Together, Mark and David traveled 570 miles to the beach. If Mark traveled 255 miles, how fr did David travel?
Together, Mark and David traveled 570 miles to the beach. If Mark traveled 255 miles, how fr did David travel?
The equation that could be used to solve this problem is:
Mark's distance + David's distance = Total distance
Let's assign variables to the distances:
Let M represent Mark's distance.
Let D represent David's distance.
Let T represent the total distance.
The equation would then be:
M + D = T
Since we know Mark traveled 255 miles and the total distance is 570 miles, we can substitute these values into the equation:
255 + D = 570
Now we can solve for D by subtracting 255 from both sides of the equation:
D = 570 - 255
D = 315
Therefore, David traveled 315 miles.
Mark's distance + David's distance = Total distance
Let's assign variables to the distances:
Let M represent Mark's distance.
Let D represent David's distance.
Let T represent the total distance.
The equation would then be:
M + D = T
Since we know Mark traveled 255 miles and the total distance is 570 miles, we can substitute these values into the equation:
255 + D = 570
Now we can solve for D by subtracting 255 from both sides of the equation:
D = 570 - 255
D = 315
Therefore, David traveled 315 miles.
What is the value of x when -3x + 9 = -19?
To find the value of x, we need to solve the equation -3x + 9 = -19.
First, let's isolate the variable -3x by subtracting 9 from both sides of the equation:
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Next, we can solve for x by dividing both sides of the equation by -3:
(-3x) / -3 = (-28) / -3
This simplifies to:
x = 28/3 or approximately 9.33
Therefore, the value of x is approximately 9.33.
First, let's isolate the variable -3x by subtracting 9 from both sides of the equation:
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Next, we can solve for x by dividing both sides of the equation by -3:
(-3x) / -3 = (-28) / -3
This simplifies to:
x = 28/3 or approximately 9.33
Therefore, the value of x is approximately 9.33.

Apologies for the mistake. Let's solve the equation correctly:
-3x + 9 = -19
To isolate -3x, we can subtract 9 from both sides of the equation:
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Now we can solve for x by dividing both sides of the equation by -3:
-3x / -3 = -28 / -3
This simplifies to:
x = 28/3 or approximately 9.33
Therefore, the value of x is approximately 9.33.
-3x + 9 = -19
To isolate -3x, we can subtract 9 from both sides of the equation:
-3x + 9 - 9 = -19 - 9
This simplifies to:
-3x = -28
Now we can solve for x by dividing both sides of the equation by -3:
-3x / -3 = -28 / -3
This simplifies to:
x = 28/3 or approximately 9.33
Therefore, the value of x is approximately 9.33.
What is the value of x when -3x + 9 = -19?
A. -9
B. 9
C. 3 2/3
D. -3 2/3
A. -9
B. 9
C. 3 2/3
D. -3 2/3
To find the value of x when -3x + 9 = -19, we can start by isolating the variable -3x by subtracting 9 from both sides:
-3x + 9 - 9 = -19 - 9
Simplifying this equation gives us:
-3x = -28
Now, to determine the value of x, we can divide both sides of the equation by -3:
(-3x) / -3 = (-28) / -3
This results in:
x = 28/3
Therefore, the correct answer is:
C. 3 2/3
-3x + 9 - 9 = -19 - 9
Simplifying this equation gives us:
-3x = -28
Now, to determine the value of x, we can divide both sides of the equation by -3:
(-3x) / -3 = (-28) / -3
This results in:
x = 28/3
Therefore, the correct answer is:
C. 3 2/3
