Which steps are needed to solve this equation? b+6= 21

Simplify 24÷(-2)(3)+7 a. -29 b. 3 c. 11

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

Find the distance between c and d on the number line c=3 and d=11
