The high temperatures for each day last week increased by one degree each day: 65°, 66°, 67°, 68°, 69°, 70°, 71°. what was the mean temperature for the week? 68° or 65° or 71° or 70°

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

both equations and proportions are better.
