Simplify. 3 4 −4z+ 5 4 z− 1 2 + 1 2 z

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

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
