Ateacher has 15 weeks in which to teach six chapters. write and then solve an equation, showing all work, that represents the number of lessons the teacher must teach per week if there is an average of 8.5 lessons per chapter.

Arrange these numbers from least to greatest 3/5 5/7 2/9

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
