The sum of two numbers is 82. Their difference is 24. Write a system of equations that describes this situation. Solve by elimination to find the two numbers.a.x + y = 82x – y = 2448 and 24c.x + y = 24y – x = 8248 and 30b.x – y = 82x + y = 2452 and 30d.x + y = 82x – y = 2453 and 29

Suppose you have just enough money, in coins, to pay for a loaf of bread priced at $1.95. You have 12 coins, all quarters and dimes. Let q equal the number of quarters and d equal the number of dimes. Which system models the given information?a.q + d = 12q + d = 1.95c.25q + 10d = 195q + 12 = db.10q + 25d = 12q + d = 1.95d.q + d = 120.25q + 0.10d = 1.95

A family is canoeing downstream (with the current). Their speed relative to the banks of the river averages 2.75 mi/h. During the return trip, they paddle upstream (against the current), averaging 1.5 mi/h relative to the riverbank. Write and solve a system of equations to find the family’s paddling speed in still water. Let s equal the families paddling speed and c represent the current a. s + c = 2.75 s - c = 1.5 2.125 mi/h c. s + c = 2.75 c - s = 1.5 .60 mi/h b. 2.75s = c 1.5s = c 1.725 mi/h d. 2.75c = s 1.5c = s 30 mi/h Please select the best answer from the choices provided
