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)
-x = -8.7
Now, to solve for x, we can multiply both sides of the equation by -1 to isolate x:
(-1)(-x) = (-1)(-8.7)
x = 8.7
Therefore, the solution to the equation is x = 8.7. So the correct answer is A. 8.7.
