Estimate: 4 1/2 - 3 5/6

2/3

Step-by-step explanation:

1. Turn it into an improper fraction

=

=

Now find a common denominator and in this case, it can be 6

= ....

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.
