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)
x + 3.19 = ____
And what is the value of x
The equation that represents the cost of a drink is:
x + 3.19 = 5.61
To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 3.19 from both sides of the equation:
x + 3.19 - 3.19 = 5.61 - 3.19
Simplifying, we have:
x = 2.42
Therefore, the value of x, representing the cost of a drink, is $2.42.
If x/- 5 = 2 then what is
the value of x? (1 point)
To find the value of x, we can multiply both sides of the equation by -5, since dividing by -5 is the same as multiplying by -1/5. This will allow us to isolate x on one side of the equation:
(x/-5) * -5 = 2 * -5
Simplifying, we have:
x = -10
Therefore, the value of x is -10.
Which of the following pairs of equations has exactly the same solution? (1 point)
O - 3/4 * x = 5/2 5/2 * x = - 3/4 and
- 3.2x = 0.64 and x/4 = - 0.05
aligned 3 8 x=1:\\ 1/3 * x = 1/8 aligned and
x/3.2 = 1.8 and 1.8x = 3.2
To find the pair of equations that has exactly the same solution, we need to solve each pair of equations and compare the solutions.
Pair 1:
-3/4 * x = 5/2
5/2 * x = -3/4
To solve the first equation, we can multiply both sides by -4/3:
x = -10/3
For the second equation, we can multiply both sides by 2/5:
x = -3/10
The solutions for the two equations do not match, so this pair of equations does not have exactly the same solution.
Pair 2:
-3.2x = 0.64
x/4 = -0.05
To solve the first equation, we divide both sides by -3.2:
x = -0.2
For the second equation, we multiply both sides by 4:
x = -0.2
The solutions for both equations are the same, so this pair of equations has exactly the same solution.
Pair 3:
(1/3) * x = 1/8
x = 1
The solution for the first equation is x = 8/3, not 1. Therefore, this pair of equations does not have exactly the same solution.
Pair 4:
x/3.2 = 1.8
1.8x = 3.2
To solve the first equation, we multiply both sides by 3.2:
x = 5.76
The second equation is already in terms of x. Both equations have the same solution, x = 5.76.
In conclusion, the pair of equations that has exactly the same solution is:
-3.2x = 0.64
x/4 = -0.05
