Which set of ordered pairs represents a function? Group of answer choices {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(6, 8), (5, 2), (–2, –5), (1, –3), (–2, 9)} {(3, –1), (7, 1), (–6, –1), (9, 1), (2, –1)} {(–3, 1), (6, 3), (–3, 2), (–3, –3), (1, –1)}

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!
