Acontractor's crew can frame 3 houses in a week. how long will it take them to frame 54 houses if hey frame the same number each week?

It would take 18 weeks

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!
