1.What is the solution of the equation 5/2x = −1/8 ?(1 point)

2.What is the solution of the equation −x/2.9=−3 ?(1 point)Responses

3.What is the solution of the equation 8/5x = −10 ?(1 point)Responses

Answer 1

1. To solve the equation 5/2x = -1/8, we can cross-multiply.
Multiplying both sides by 2 and then dividing by 5, we have:
x = (-1/8) * (2/5)
x = -1/20

2. To solve the equation -x/2.9 = -3, we can multiply both sides by 2.9 to eliminate the fraction.
Multiplying both sides by 2.9, we have:
(-x/2.9) * 2.9 = -3 * 2.9
-x = -8.7
Dividing both sides by -1, we have:
x = 8.7

3. To solve the equation 8/5x = -10, we can cross-multiply.
Multiplying both sides by 5, we have:
(8/5x) * 5 = -10 * 5
8 = -50x
Dividing both sides by -50, we have:
x = 8/-50
x = -0.16 or -1/6
