One week later there are 45 students in the class. the theoretical probability that a random chosen student is a female is the same as last week. how many makes joined?

Please be a little more specific. I can be of some help.

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!
