the population of a city was 359,000. Several years later it was
355,410. Find the percent decrease.

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!

These are the multiples of 15 but what you are probably asking or what are the factors of 15
