The number x is reduced by 25% and then halved

Since it says the number  x , this means x represents a number , reduced by 25 means that this is most likely half of 25 so whats half of 25%?

well 5 * 5 = 25 , so here is your answer  = 5

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
