$-8 < 2 < 3$ (true or false)

Questions similar to 27–37 will show up on exams.

For questions 27 to 30, find each solution set and graph it.

Find two numbers such that 6 times the larger number plus 2 times the smaller is 38, and 4 times the larger minus twice the smaller is 12.
Karl is going to cut a 36 cm cable into 2 pieces. If the first piece is to be 5 times as long as the second piece, find the length of each piece.
