Identify the class midpoints for the given frequency distribution. a.)200 205 210 215 220 225 230 235
b.)202 207 212 217 222 227 232 237
c.)204 209 214 219 224 229 234 239
d.)202.5 207.5 212.5 217.5 222.5 227.5 232.5 237.5

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!
