 Example: "Some number added to 7 gives 11," convert this word problem into a symbolic statement. Solution: Let the number be 'x'. If x is added to 7, we get x+7. According to the problem statement, this sum is equal to 11. Therefore, symbolically the statement is x+7 = 11. Directions: Convert the following word problems into symbolic statements. Also write at least 10 examples of your own.
 Q 1: 7 times a number gives 49.x = 49*7x + 7 = 497x = 497/x = 49 Q 2: Some number added to 15 gives 20.x + 15 = 20x = 15 + 20x + 20 = 1515x = 20 Q 3: Some number decreased by 50 gives 35.x = 35 - 50x + 50 = 35x - 50 = 35x + 35 = 50 Q 4: 75 reduced by some number gives 37.37 - x = 7575 - x = 37x = 75 - 37x - 75 = 37 Q 5: Some number added to 20 gives 11.x + 20 = 11x + 11 = 20x = 20 + 1120x = 11 Q 6: 50 reduced by some number gives 45.x - 50 = 4550 - x = 45x = 50 - 4545 - x = 50 Question 7: This question is available to subscribers only!
