At sea level, the speed of sound in air is linearly related to the air temperature. If it is 35 degrees C, sound will travel at a rate of 352 meters per second. If it is 15 degrees
C, sound will travel at a rate of 340 meters per second. Write a linear equation that
models speed of sound, s in terms of air temperature, T.

Icould really use some with this question.

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

Tyler reads 2/5 of a book on monday, 1/3 of it on tuesday, 2/9 of it on wednesday, and 3/4 of the remainder on thursday. if he still has 14 pages left to read on friday, how many pages are there in the book?
