Question

26. 44.5 < 2.7d
=d> 16 13/27

27. -17.1m <23.8
=m>-1 67/171

28. You earn $7.25 per hour baby-sitting. Write and solve and inequality to find how many full hours you must work to earn $200.
=7.25 h > 200 at least 28 hours.

Please explain.

Answer 1

26. first, try to isolate "d". to do this, you would divide 2.7 from both sides:

27: same as 26 except this time you want to isolate the m. REMEMBER: whenever you divide by a negative number, always switch the inequality sign. for this one, your final answer would be m > -14

28: you earn 7.25x where x represents hours. 7.25x > 200 because you must earn greater than 7.25x to earn 200
