If 10 + x is more than 10, what is the value of 2x? - 10 The result when a number is divided by 2 is equal to the result when that same number is divided by 4. What is that number? - 0 In a certain store, the regular price of a refrigerator is $600. How much money is saved by buying this refrigerator at 20 percent off the regular price rather than buying it on sale at 10 percent off the regular price with an additional discount of 10 percent off the sale price? - $6 If the func...
