To solve for x in the equation x/12 = 6, you need to perform the same operation on both sides of the equation. In this case, you should multiply both sides of the equation by 12.
What is the solution of the equation 5/2x = −1/8 ?(1 point)
To solve the equation 5/2x = -1/8, you can start by multiplying both sides of the equation by the reciprocal of 5/2, which is 2/5.
(2/5)(5/2x) = (2/5)(-1/8)
1x = -2/40
Now, simplify the right side of the equation:
x = -1/20
So, the solution to the equation 5/2x = -1/8 is x = -1/20.
What is the solution of the equation −x/2.9=−3 ?(1 point)
To solve the equation -x/2.9 = -3, you can start by multiplying both sides of the equation by 2.9 to eliminate the denominator:
2.9 * (-x/2.9) = 2.9 * (-3)
This simplifies to:
-x = -8.7
To isolate x, you can multiply both sides of the equation by -1, which will switch the signs:
(-1)(-x) = (-1)(-8.7)
This simplifies to:
x = 8.7
So, the solution to the equation -x/2.9 = -3 is x = 8.7.
What is the solution of the equation 85x = −10 ?(1 point)
To solve the equation 85x = -10, you can start by dividing both sides of the equation by 85 to isolate x:
(85x)/85 = (-10)/85
This simplifies to:
x = -10/85
The fraction -10/85 cannot be simplified further, so the solution to the equation 85x = -10 is x = -10/85.
