To solve the equation 5/2x = -1/8, we can start by multiplying both sides of the equation by the reciprocal of 5/2, which is 2/5. This cancels out the coefficient on the variable x.
(2/5) * (5/2x) = (2/5) * (-1/8)
1/x = -2/40
Simplifying further, we get:
1/x = -1/20
The value of x that satisfies this equation is -1/20. Therefore, the correct solution is -1/20.
(2/5) * (5/2x) = (2/5) * (-1/8)
1/x = -2/40
Simplifying further, we get:
1/x = -1/20
The value of x that satisfies this equation is -1/20. Therefore, the correct solution is -1/20.

To solve the equation -x/2.9 = -3, we can start by multiplying both sides of the equation by 2.9 to eliminate the fraction.
2.9 * (-x/2.9) = 2.9 * (-3)
This simplifies to:
-x = -8.7
To isolate x, we can multiply both sides of the equation by -1 to change the sign of the equation.
(-1) * (-x) = (-1) * (-8.7)
This simplifies to:
x = 8.7
Therefore, the correct solution is x = 8.7.
2.9 * (-x/2.9) = 2.9 * (-3)
This simplifies to:
-x = -8.7
To isolate x, we can multiply both sides of the equation by -1 to change the sign of the equation.
(-1) * (-x) = (-1) * (-8.7)
This simplifies to:
x = 8.7
Therefore, the correct solution is x = 8.7.

To solve the equation 8/5x = -10, we can begin by multiplying both sides of the equation by the reciprocal of 8/5, which is 5/8. This will cancel out the coefficient on the variable x.
(5/8) * (8/5x) = (5/8) * (-10)
1/x = -50/8
To simplify this further, we can divide both the numerator and the denominator of -50/8 by their greatest common divisor, which is 2.
(1/x) = (-25/4)
Thus, the solution of the equation is x = -4/25, or -1/16.
Therefore, the correct response is −1/16.
(5/8) * (8/5x) = (5/8) * (-10)
1/x = -50/8
To simplify this further, we can divide both the numerator and the denominator of -50/8 by their greatest common divisor, which is 2.
(1/x) = (-25/4)
Thus, the solution of the equation is x = -4/25, or -1/16.
Therefore, the correct response is −1/16.

Let's assign the variable a to represent Justin's age.
We are given that Kendra's age is half the age of Justin, which can be represented as a/2.
We are also given that Kendra is 13 years old, so we can set up the equation:
a/2 = 13
To find Justin's age, we need to solve for a. We can do this by multiplying both sides of the equation by 2:
2 * (a/2) = 2 * 13
This simplifies to:
a = 26
Therefore, the correct equation that represents Justin's age is 2a = 13.

Apologies for the confusion. Let's analyze the equation 1/2a = 13.
To find Justin's age, we can multiply both sides of the equation by 2 to cancel out the fraction:
2 * (1/2a) = 2 * 13
This simplifies to:
1/a = 26
Therefore, the correct equation that represents Justin's age is 1/a = 26.
Thank you for pointing out the correct answer.

Apologies for the misunderstanding. Let's reassess the equation 1/2a = 13.
If Kendra's age is 13, we can set up the equation:
1/2a = 13
To find Justin's age, we can solve for a. We can do this by multiplying both sides of the equation by 2:
2 * (1/2a) = 2 * 13
This simplifies to:
1/a = 26
Therefore, the correct equation that represents Justin's age is 1/a = 26.
