Consider the steps to simplify the expression. what property of operation is used in step 2? expression: -4 3 7 + 7 - 3 4 7 step 1: = -4 3 7 + 7 + (-3 4 7 ) step 2: = -4 3 7 + (-3 4 7 ) + 7 step 3: = -4 + (- 3 7 ) + (-3) + (- 4 7 ) + 7 step 4: = -4 + (- 3 7 ) + (- 4 7 ) + (-3) + 7 step 5: = -4 + (-1) + (-3) + 7 step 6: = -8 + 7 step 7: = -1

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
