Which of the following equations has a different value of x than the others?(1 point)
Responses
x + 9/8 = 7/4
x - 7/8 = -3/2
x + 0.875 = 1.5
x - 0.025 = 0.6
x + 9/8 = 7/4
If x/-5 = 2, then what is the value of x?
To find the value of x, we can multiply both sides of the equation by -5 to isolate x:
x/-5 * -5 = 2 * -5
This simplifies to:
x = -10
Therefore, the value of x is -10.

−3.2x=0.64 and x/4=−0.05
−3/4 x = 5/2 and 5/2 x = −3/4
3/8 x = 1 and 1/3 x = 1/8
x/3.2 = 1.8 and 1.8 x =3.2
The pair of equations that has exactly the same solution is:
−3/4 x = 5/2 and 5/2 x = −3/4

The temperature dropped by 12° in 5 hours. The temperature dropped the same amount every hour. Complete the equation that represents the amount of change, x , of temperature every hour and solve this equation.(1 point)
5x=
The temperature decreased by ° every hour.
To solve the equation 5x=12, we can divide both sides of the equation by 5:
5x/5 = 12/5
This simplifies to:
x = 2.4
Therefore, the temperature decreased by 2.4° every hour.
