To solve for u in the equation -10.3 = u/8 + 2.5, we need to isolate u on one side of the equation.
First, we can subtract 2.5 from both sides of the equation:
-10.3 - 2.5 = u/8
-12.8 = u/8
Next, we can multiply both sides of the equation by 8 to eliminate the fraction:
8 * -12.8 = 8 * (u/8)
-102.4 = u
Therefore, the value of u is -102.4.
-10.3 = u/8 + 2.5
