23. there is a shaved ice shack on 600 south street. both mary and lina live on 600 south street. mary
lives 5 blocks west of the shack and lina lives 3 blocks east of it. how far apart do they live?
expression:

8 blocks

Step-by-step explanation:

since east and west are in opposite directions, you need to add 3 and 5 (each distance to the shack)

the correct answer is 45x

9×5=45 then add the x

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
