Which of the following equations has a different value of x than the others?(1 point)
x+ 0.875=1.5
x+ 9/8=7/4
x-7/8=-3/2
x-0.025=0.6
To determine which equation has a different value of x, we need to solve each equation for x and compare the values.
1) x + 0.875 = 1.5
Subtracting 0.875 from both sides, we get: x = 1.5 - 0.875 = 0.625
2) x + 9/8 = 7/4
Subtracting 9/8 from both sides, we get: x = 7/4 - 9/8 = 3.5/2 - 9/8 = 7/4 - 9/8 = 7/4 - 1.125 = 1.875
3) x - 7/8 = -3/2
Adding 7/8 to both sides, we get: x = -3/2 + 7/8 = -12/8 + 7/8 = -5/8
4) x - 0.025 = 0.6
Adding 0.025 to both sides, we get: x = 0.6 + 0.025 = 0.625
The equation x - 7/8 = -3/2 has a different value of x than the others, which is -5/8.
To determine which equation has a different value of x than the others, we need to solve each equation for x and compare the values.
Let's solve each equation step by step:
1) x + 0.875 = 1.5
Subtract 0.875 from both sides:
x = 1.5 - 0.875
x = 0.625
2) x + (9/8) = (7/4)
Subtract (9/8) from both sides:
x = (7/4) - (9/8)
To subtract fractions, we need a common denominator, which is 8 in this case:
x = (14/8) - (9/8)
x = 5/8
3) x - (7/8) = (-3/2)
Add (7/8) to both sides:
x = (-3/2) + (7/8)
To add fractions, we need a common denominator, which is 8 in this case:
x = (-12/8) + (7/8)
x = (-5/8)
4) x - 0.025 = 0.6
Add 0.025 to both sides:
x = 0.6 + 0.025
x = 0.625
After solving each equation, we can see that only equation 3) has a different value for x, which is -5/8. Therefore, the equation x - 7/8 = -3/2 has a different value of x than the others.
A slice of pizza costs $3.19 and a drink costs $x . The cost of a slice of pizza and a drink together is $5.61 . Complete and solve the equation that represents the cost of a drink.(1 point)
Let's represent the cost of the drink as "x" (since the problem states it is $x).
The cost of a slice of pizza is $3.19.
The cost of a slice of pizza and a drink together is $5.61.
Therefore, the equation representing the cost of a drink can be written as:
3.19 + x = 5.61
To solve for x, we need to isolate the variable x by subtracting 3.19 from both sides:
x = 5.61 - 3.19
Simplifying, we get:
x = 2.42
So, the cost of the drink is $2.42.
x+ 3.19= what
The equation x + 3.19 = ? does not specify a given value or expression to solve for. Without additional information, we cannot solve for a specific value.

To represent the cost of a drink, let's assign it as "x" (since the problem states it costs $x).
The cost of a slice of pizza is $3.19.
The cost of a slice of pizza and a drink together is $5.61.
Therefore, the equation representing the cost of a drink can be written as:
x + 3.19 = 5.61
To solve for x, we need to isolate the variable x by subtracting 3.19 from both sides:
x = 5.61 - 3.19
Simplifying, we get:
x = 2.42
So, the cost of the drink is $2.42.
If x−5=2 , then what is the value of x
To find the value of x, we need to solve the equation x - 5 = 2.
To isolate x, we can add 5 to both sides of the equation:
x - 5 + 5 = 2 + 5
This simplifies to:
x = 7
Therefore, the value of x is 7.
