Which of the following equations has a different value of x than the others? (1 point)
A. x+ 9/8=7/4
B. x+0.875=1.5
C. x-0.025=0.6
D. x-7/8=-3/2
To find the equation that has a different value of x, we need to solve each equation and compare the values of x.
A. x + 9/8 = 7/4
We can start by subtracting 9/8 from both sides:
x = 7/4 - 9/8
x = 14/8 - 9/8
x = 5/8
So for equation A, x = 5/8.
B. x + 0.875 = 1.5
We can start by subtracting 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
So for equation B, x = 0.625.
C. x - 0.025 = 0.6
We can start by adding 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
So for equation C, x = 0.625.
D. x - 7/8 = -3/2
We can start by adding 7/8 to both sides:
x = -3/2 + 7/8
x = -12/8 + 7/8
x = -5/8
So for equation D, x = -5/8.
Comparing the values of x for each equation, we can see that equation A has a different value of x than the others. Therefore, the answer is A.

Based on the provided responses, it seems like you have provided answers for a different set of questions. Unfortunately, I cannot determine the correct answer without the original questions. If you can provide the original set of questions, I would be happy to assist you further.
To determine which equation has a different value of x than the others, we need to solve each equation for x and compare the solutions.
Let's solve each equation step by step:
A. x + 9/8 = 7/4:
To solve this equation, we need to isolate x. First, subtract 9/8 from both sides:
x = 7/4 - 9/8
Next, find a common denominator and simplify:
x = 14/8 - 9/8
x = 5/8
B. x + 0.875 = 1.5:
To solve this equation, we again need to isolate x. First, subtract 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
C. x - 0.025 = 0.6:
To solve this equation, we isolate x by adding 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
D. x - 7/8 = -3/2:
To solve this equation, we isolate x by adding 7/8 to both sides:
x = -3/2 + 7/8
Finding a common denominator and simplifying:
x = -12/8 + 7/8
x = -5/8
Now, let's compare the solutions:
In equation A, we found that x = 5/8.
In equation B, we found that x = 0.625.
In equation C, we also found that x = 0.625.
In equation D, we found that x = -5/8.
Comparing the solutions, we can see that the value of x in equation D (-5/8) is different from the values in equations A, B, and C (5/8 or 0.625). Therefore, the equation that has a different value of x than the others is D.
