Tom weighs 168.5 pounds his two year old son weighs 33.7 pounds hiw many times as much as nicholas does tom weigh

168.5 / 33.7 = 5

so Tom weighs 5 times as much as Nicholas

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!
