which of the following four equations has the solution of the lowest valuse.
x+25=2
x-6=16
x+19=-5
x-7=28
The equations are as follows:
1) x + 25 = 2
2) x - 6 = 16
3) x + 19 = -5
4) x - 7 = 28
To find the solution with the lowest value, we need to solve each equation and compare the values of x.
1) x + 25 = 2
Subtract 25 from both sides:
x = 2 - 25
x = -23
2) x - 6 = 16
Add 6 to both sides:
x = 16 + 6
x = 22
3) x + 19 = -5
Subtract 19 from both sides:
x = -5 - 19
x = -24
4) x - 7 = 28
Add 7 to both sides:
x = 28 + 7
x = 35
Comparing the values of x from each equation, we can see that the equation with the lowest solution value is:
x = -24 (from equation 3: x + 19 = -5).
which of the following equations has a different value of x than the others?
x-7/8=- 3/2
x+9/8=7/4
x-.025=.6
x+.0875=1.5
To find the equation that has a different value of x than the others, we need to solve each equation and compare the values of x.
1) x - 7/8 = -3/2
To isolate x, we add 7/8 to both sides:
x = -3/2 + 7/8
2) x + 9/8 = 7/4
To isolate x, we subtract 9/8 from both sides:
x = 7/4 - 9/8
3) x - 0.025 = 0.6
To isolate x, we add 0.025 to both sides:
x = 0.6 + 0.025
4) x + 0.0875 = 1.5
To isolate x, we subtract 0.0875 from both sides:
x = 1.5 - 0.0875
Now we can compare the values of x from each equation:
1) x = -3/2 + 7/8
2) x = 7/4 - 9/8
3) x = 0.6 + 0.025
4) x = 1.5 - 0.0875
By comparing the values of x, we can see that the equation with a different value of x is:
x = 0.6 + 0.025 (from equation 3: x - 0.025 = 0.6).
If x/-5 = 2 then what is the value of x
To solve for x in the equation x/-5 = 2, we can multiply both sides by -5:
(x/-5)(-5) = 2(-5)
Simplifying, we get:
x = -10
Therefore, the value of x is -10.
Which of the following pairs of equations has exaly the same solution?
- 3/4x+5/2 and 5/2x=3/4
x/3.2=1.8 and 1.8=3.2
3/8x=1 and 1/3x=1/8
-3.2=.64 and x/4=-.05
To determine which pair of equations has exactly the same solution, we need to solve each pair of equations separately.
1) -3/4x + 5/2 and 5/2x = 3/4
Simplifying the first equation, we have:
-3/4x + 5/2 = 0
To solve for x, we can subtract 5/2 from both sides:
-3/4x = -5/2
Now, multiply both sides by -4/3 to isolate x:
x = (-5/2) * (-4/3)
x = 10/3
For the second equation, we have:
5/2x = 3/4
We can multiply both sides by 2/5:
x = (3/4) * (2/5)
x = 6/20
x = 3/10
The solutions for the first equation and the second equation are x = 10/3 and x = 3/10, respectively. These solutions are not the same.
2) x/3.2 = 1.8 and 1.8 = 3.2
For the first equation, we have:
x/3.2 = 1.8
To solve for x, we can multiply both sides by 3.2:
x = 3.2 * 1.8
x = 5.76
For the second equation, we have:
1.8 = 3.2
This equation states that 1.8 is equal to 3.2. However, this is not true, so this equation does not have a solution.
3) 3/8x = 1 and 1/3x = 1/8
For the first equation, we have:
3/8x = 1
To solve for x, we can multiply both sides by 8/3:
x = (1) * (8/3)
x = 8/3
For the second equation, we have:
1/3x = 1/8
To solve for x, we can multiply both sides by 8/1:
x = (1/8) * (8/1)
x = 1
The solutions for the first equation and the second equation are x = 8/3 and x = 1, respectively. These solutions are not the same.
4) -3.2 = .64 and x/4 = -.05
For the first equation, we have:
-3.2 = .64
This equation states that -3.2 is equal to 0.64. However, this is not true, so this equation does not have a solution.
For the second equation, we have:
x/4 = -0.05
To solve for x, we can multiply both sides by 4:
x = -0.05 * 4
x = -0.2
The solutions for the first equation and the second equation are not the same.
Therefore, none of the pairs of equations have the same solution.
Which of the following equations has a solution of -7?
4x-23=5
-3x-8=-29
5x+11=-24
-x+3=-4
To determine which equation has a solution of -7, we can substitute -7 for x in each equation and see which one satisfies the equation.
1) 4x - 23 = 5
Substituting -7 for x:
4(-7) - 23 = 5
-28 - 23 = 5
-51 = 5
This equation is not true when x = -7.
2) -3x - 8 = -29
Substituting -7 for x:
-3(-7) - 8 = -29
21 - 8 = -29
13 = -29
This equation is not true when x = -7.
3) 5x + 11 = -24
Substituting -7 for x:
5(-7) + 11 = -24
-35 + 11 = -24
-24 = -24
This equation is true when x = -7.
4) -x + 3 = -4
Substituting -7 for x:
-(-7) + 3 = -4
7 + 3 = -4
10 = -4
This equation is not true when x = -7.
Out of the given equations, only the equation 5x + 11 = -24 has a solution of x = -7.
