Penelope is playing a number game with her sister June. Penelope is thinking of a number and wants June to guess it. Five more thank three times a number is between 23 and 32. Write a compound inequality that shows the range of numbers that Penelope might be thinking of. Use x for your variable.
Answered by cain
a compound inequality would mean like

a number < x < a number

you know that the number is between 23 and 32

23 < x < 32

but its not just x, its 3x +5

23 < 3x + 5 < 32
